Product details
Overview
MAX16712AWI+ from Analog Devices is a dual-output, fully integrated step-down DC-DC switching regulator delivering up to 6A per output (12A in dual-phase mode), operating from 2.7V to 16V input, with configurable 500kHz–2MHz switching frequency and 0.5V–5.8V output voltage range. It integrates fixed-frequency current-mode control, 180° out-of-phase operation, and internal 1.8V LDO for gate drive and analog bias-designed for high-density POL regulation in FPGA I/O, memory VDDQ, and μP chipset power.
For engineers reviewing the MAX16712AWI+ datasheet, MAX16712AWI+ pinout, MAX16712AWI+ application, or MAX16712AWI+ equivalent, this page delivers verified technical context, validated pin functions, confirmed dual-phase vs. dual-output behavior, real-world efficiency curves at 12V/1.2V/1MHz, and two rigorously cross-checked alternative regulators with documented functional trade-offs.
Technical Context
The MAX16712AWI+ implements fixed-frequency peak current-mode control with internal compensation and 180° interleaved phase alignment between its two synchronous buck regulators. Its advanced modulation scheme (AMS) enables leading- and trailing-edge modulation during load transients to extend closed-loop bandwidth to 140kHz (phase margin 57°) without sacrificing stability.
It supports pin-strapped configuration via PGM0 (32-level resistor-programmable switching frequency and scenario selection), PGM1/PGM2 (3-level POCP threshold selection: 4.5A/6A/9A per output), and SNSP2-to-AVDD connection to enable dual-phase mode-where only OUTPUT1's control loop remains active and EN2/PGOOD2 are unused.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 16V - supports wide-input industrial and telecom rails without external pre-regulation. |
| Output Current (per output) | 6A continuous - enables single-chip dual-rail supply for FPGA I/O banks or DDR memory termination. |
| Switching Frequency | 500kHz to 2.0MHz - selectable via PGM0 resistor; higher frequencies reduce inductor size (e.g., 1MHz enables ≤1.0μH inductors). |
| Output Voltage Range | 0.5V to 5.8V - covers core logic (0.8V), I/O (1.2V/1.8V/3.3V), and analog subsystems (5.0V) with ±1% reference accuracy. |
| Junction Temperature Range | −40°C to +125°C - qualified for extended-temperature industrial and networking equipment deployment. |
| Peak Efficiency | 90.5% at 12VIN/1.8VOUT/1MHz - achieved with internal MOSFETs and optimized gate drive, reducing thermal design burden. |
| Package | 2.2mm × 3.5mm, 28-bump WLP - ultra-compact footprint ideal for space-constrained BGA-based systems. |
Pinout & Package
MAX16712AWI+ uses a 2.2mm × 3.5mm wafer-level package (WLP) with 28 solder bumps arranged in a 7×4 grid. The package supports −40°C to +125°C junction temperature operation and requires JEDEC-compliant reflow profile (peak 260°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BST1, BST2 | Bootstrap supply for high-side MOSFET gates | Each requires 0.22μF ceramic capacitor to respective LX node; enables efficient 100% duty-cycle capability. |
| VDDH1, VDDH2 | Main input power supply pins | Must be shorted on PCB; supplies both buck channels and internal LDO-no separate bias required. |
| LX1, LX2 | Switching node outputs | Direct connection point to external power inductors; high di/dt routing demands tight layout and low-inductance PGND return. |
| SNSP1, SNSP2 | Output voltage feedback inputs | Connect directly to load for accurate remote sensing; SNSP2 tied to AVDD configures dual-phase mode. |
| EN1, EN2 | Independent enable inputs | Active-high with 0.6V/0.9V thresholds; EN2 is unused in dual-phase mode per datasheet configuration rules. |
| PGOOD1, PGOOD2 | Open-drain power-good status indicators | Asserted after soft-start (3ms) and valid output regulation; each monitors only its associated output in dual-output mode. |
| PGM0, PGM1, PGM2 | Configuration programming inputs | PGM0 sets fSW and operating scenario; PGM1/PGM2 select POCP thresholds (4.5A/6A/9A); all resistively strapped to AGND/AVDD/open. |
| VCC, AVDD | Internal LDO outputs | VCC = 1.8V (±5%) for gate drivers; AVDD = 1.8V (via 2.2Ω–4.7Ω resistor from VCC) for analog circuitry-both require local decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-output or dual-phase operation | Single chip supports either independent 6A rails (e.g., VDDQ + VCCIO) or 12A single rail (e.g., GPU core) with active current balancing. |
| Advanced Modulation Scheme (AMS) | Extends transient response bandwidth by modulating both edges of PWM signal-reducing output voltage deviation by >40% vs. standard PWM under 1A/μs load steps. |
| Selectably enabled DCM | Improves light-load efficiency: at 100mA output, DCM reduces quiescent current and ripple vs. CCM; exits automatically above 100mA valley current. |
| Integrated 1.8V LDO (VCC/AVDD) | Eliminates need for external bias supply-VCC powers gate drivers, AVDD powers analog core; both require specified decoupling per pin description. |
| Three-level POCP programming | PGM1 selects per-output overcurrent threshold (4.5A/6A/9A); enables precise matching to inductor saturation limits and system fault tolerance requirements. |
Applications
| FPGA I/O Power | DDR Memory VDDQ |
|---|---|
Use Scenario: Supplying configurable I/O banks on Xilinx Versal or Intel Agilex FPGAs requiring multiple independent 1.2V/1.8V/3.3V rails with fast transient response. IC Role / Device Role / Timing Role: Dual-output buck regulator delivering 6A per rail with independent enable and PGOOD signaling-enabling staggered power-up sequencing and rail-specific fault isolation. Use Value: Eliminates need for two discrete 6A regulators; AMS ensures <15mV undershoot during 4A/μs I/O switching transients at 1.2V output. |
Use Scenario: Providing tightly regulated 1.2V VDDQ for DDR4/DDR5 memory interfaces in servers and AI accelerators where voltage accuracy and noise immunity are critical.

Use Value: Achieves <±1% output regulation across −40°C to +125°C; dual-phase ripple cancellation lowers output capacitor count by 30% vs. single-phase implementation. |
| μP Chipset Core Power | Networking ASIC Auxiliary Rails |
Use Scenario: Delivering 0.8V/6A core voltage to AMD EPYC or Intel Xeon Scalable processors' auxiliary power domains with strict PSRR and transient requirements. IC Role / Device Role / Timing Role: Dual-output regulator configured as primary 0.8V/6A core rail + secondary 1.8V/3A I/O rail-sharing input capacitance and thermal path while maintaining independent regulation. Use Value: Internal compensation and fixed 0.5V reference ensure ±0.5% load regulation from 0–6A; 140kHz bandwidth rejects high-frequency noise from adjacent high-speed SerDes lanes. |
Use Scenario: Generating 3.3V and 5.0V auxiliary rails for packet processing ASICs in 5G baseband units where board space and thermal density are constrained. IC Role / Device Role / Timing Role: Dual-output buck supplying 3.3V/4A (OUTPUT1) and 5.0V/3A (OUTPUT2) from common 12V backplane-leveraging shared control logic and thermal management. Use Value: Configurable fSW allows optimization: 500kHz for lowest EMI in sensitive RF sections; 2MHz for minimal inductor size in dense control-plane modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4485GQ-AEC1-Z | Automotive-grade (AEC-Q100), 4A per channel, 2.5V–18V input, but no dual-phase mode or AMS; uses external compensation. | Requires external loop compensation components and lacks active current balancing-less suitable for high-current single-rail applications. | Preferred for automotive infotainment SoC power where AEC-Q100 qualification is mandatory and 4A/channel suffices. |
| TPS546D24RQFR | 6A per channel, 3V–18V input, PMBus interface, digital control, and telemetry-but larger 5mm × 5.5mm QFN package and higher BOM cost. | Supports real-time telemetry and dynamic voltage scaling (DVS), but adds firmware integration complexity and layout area. | Chosen when system-level power management (e.g., adaptive voltage scaling for AI workloads) justifies digital control overhead. |
Compared with MAX16712AWI+, MPQ4485GQ-AEC1-Z trades dual-phase capability and AMS for automotive qualification, while TPS546D24RQFR replaces analog simplicity with digital configurability and telemetry-at the cost of increased design effort and footprint.

FAQ
What is the maximum output current capability of the MAX16712AWI+ in dual-phase mode?
The MAX16712AWI+ supports up to 12A total output current in dual-phase mode, achieved by connecting SNSP2 to AVDD. This configuration uses interleaved 180° switching and active current balancing to maintain phase current match within ±5% across load transients, as verified in Figure toc18 and toc19 of the datasheet. Each phase contributes nominally 6A, but thermal derating applies per SOA curves (e.g., 10A at +85°C ambient, no airflow).
How does the Advanced Modulation Scheme (AMS) improve transient response in the MAX16712AWI+?
The AMS in MAX16712AWI+ dynamically modulates both leading and trailing edges of the PWM signal during large load steps, effectively increasing control loop bandwidth to 140kHz (Figure toc20) without phase-margin degradation. This reduces output voltage deviation by >40% compared to conventional fixed-frequency PWM under 1A/μs transients, as demonstrated in Figure toc17 and toc18-directly enabling smaller output capacitance and faster recovery in FPGA I/O and memory VDDQ applications.
Can the MAX16712AWI+ operate with a 2.5V input supply?
No, the MAX16712AWI+ has a minimum input voltage of 2.7V as specified in Absolute Maximum Ratings and Electrical Characteristics tables. Operation below 2.7V violates the VDDH UVLO rising threshold (2.4V–2.6V), causing immediate shutdown and PGOOD assertion failure. For 2.5V input systems, an upstream boost stage or alternative regulator with lower VIN min (e.g., TPS62864) is required.
What is the purpose of the PGM0 pin on the MAX16712AWI+, and how is it used?
The PGM0 pin on MAX16712AWI+ is a resistor-programmable input that selects both switching frequency (500kHz–2MHz) and predefined operating scenarios (e.g., DCM enable/disable, slope compensation settings) via 32 discrete resistance codes (0.095kΩ–115kΩ). As detailed in Table 1 and Pin Descriptions, PGM0 must be connected to AGND through a precision resistor-its value determines fSW and control-loop behavior without requiring digital interface or external clock sources.
Does the MAX16712AWI+ support pre-biased output startup?
Yes, the MAX16712AWI+ supports smooth pre-biased startup, as confirmed in Figure toc13 and Startup and Shutdown section (page 12). When the output is pre-biased (e.g., VPREBIAS = 0.5V), the IC disables reverse current flow in the low-side MOSFET during soft-start, preventing output voltage collapse and ensuring monotonic ramp-up-even with external voltage present on VOUT1/VOUT2 prior to EN assertion.
