Product details
Overview
MAX16712AWI+T 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° interleaved operation, and internal 1.8V LDO for gate drive and analog circuitry - deployed in high-density POL applications for FPGAs, μP chipsets, and memory VDDQ rails.
For engineers reviewing the MAX16712AWI+T datasheet, MAX16712AWI+T pinout, MAX16712AWI+T application, or MAX16712AWI+T equivalent, key selection considerations include dual-output vs. dual-phase configuration flexibility, programmable POCP thresholds (4.5A/6A/9A), AMS-enhanced transient response, DCM-selectable light-load efficiency, and thermal performance across -40°C to +125°C junction temperature.
Technical Context
The MAX16712AWI+T implements fixed-frequency peak current-mode control with internal compensation and dual independent control loops - each featuring a 0.5V reference, error amplifier, slope-compensated PWM comparator, and AMS-enabled leading/trailing-edge modulation. Its 180° phase shift between outputs reduces input/output ripple and improves dynamic current sharing.
Configuration is set at startup via three pin-strapped inputs: PGM0 selects switching frequency (500kHz–2MHz) and predefined operational scenario; PGM1/PGM2 configure per-output POCP thresholds (4.5A/6A/9A); SNSP2 connection to AVDD enables dual-phase mode, disabling OUTPUT2's control loop and consolidating enable/power-good to EN1/PGOOD1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 16V - supports wide industrial and computing supply rails including 3.3V, 5V, 12V intermediate buses. |
| Output Current per Channel | 6A continuous - enables single-chip dual-rail power delivery for core and I/O domains of modern SoCs/FPGAs. |
| Switching Frequency | 500kHz to 2.0MHz - selectable via PGM0 resistor; higher frequencies allow smaller inductors/capacitors for compact POL designs. |
| Output Voltage Range | 0.5V to 5.8V - covers DDR memory VDDQ (1.2V/1.35V), CPU cores (0.8V–1.2V), and I/O supplies (1.8V/3.3V). |
| Junction Temperature Range | -40°C to +125°C - rated for harsh environments; guaranteed 90k hours at 6A/85°C junction temp with 12VIN/1.2VOUT. |
| Peak Efficiency | 90.5% at 12VIN, 1.8VOUT, 1MHz - achieved via low-RDS(on) integrated MOSFETs and optimized gate drive architecture. |
| Protection Features | Positive/negative OCP, OVP, OTP, VDDH UVLO/OVLO - hiccup-mode fault recovery ensures robustness without external supervision circuitry. |
Pinout & Package
MAX16712AWI+T is housed in a compact 2.2mm × 3.5mm, 28-bump wafer-level package (WLP) with 0.4mm pitch, optimized for high-density PCB layouts and thermal performance (θJA = 27.3°C/W on EVKIT, no heatsink/no airflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BST1, BST2 | Bootstrap supply for high-side MOSFET gates | Requires 0.22μF ceramic capacitor to respective LX pin; enables efficient 100% duty-cycle capability and stable gate drive. |
| SNSP1, SNSP2 | Output voltage sense feedback inputs | Connect directly to load for accurate regulation; tie SNSP2 to AVDD to enable dual-phase mode and disable OUTPUT2 control loop. |
| EN1, EN2 | Independent enable inputs | Active-high logic; EN2 is unused in dual-phase mode; rising threshold = 0.9V, falling = 0.6V with 200μs filtering delay. |
| PGOOD1, PGOOD2 | Open-drain power-good status outputs | Asserted after soft-start (3ms ramp); pulled low during faults (OVP, OCP, OTP); require external pull-up resistor. |
| PGM0, PGM1, PGM2 | Configuration programming inputs | PGM0 sets fSW and scenario via resistor to AGND; PGM1/PGM2 select POCP thresholds (4.5A/6A/9A) per output. |
| VCC, AVDD | Internal LDO outputs | VCC = 1.8V ±5% (80mA limit) powers gate drivers; AVDD = 1.8V supplied via 2.2Ω–4.7Ω resistor from VCC, powers analog core. |
Key Features
| Feature | Design Value |
|---|---|
| Advanced Modulation Scheme (AMS) | Enables simultaneous leading/trailing-edge modulation during load transients - extends closed-loop bandwidth to 140kHz (57° phase margin) and minimizes output capacitance requirements. |
| Dual-phase current balancing | Active real-time adjustment of phase-current control signals maintains ≤5% current imbalance during fast load steps, even near switching frequency harmonics. |
| Selectable DCM operation | Automatically transitions to discontinuous conduction mode below ~100mA valley current - improves light-load efficiency by reducing switching losses. |
| Integrated 1.8V bias LDO | Eliminates need for external bias supply: VCC powers gate drivers; AVDD (derived via series resistor) powers analog circuitry - reduces BOM count and layout complexity. |
| Pre-biased startup support | Smoothly ramps output from pre-existing voltage (e.g., 0.5V) without reverse current flow - critical for hot-swap and multi-rail sequencing applications. |
Applications
| FPGA Core & I/O Power | Server Memory Subsystem |

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-P | Automotive-grade (AEC-Q100), 2.5V–18V input, 6A per channel, but fixed 750kHz fSW; no AMS or DCM; requires external compensation. | Targeted at automotive infotainment and ADAS; lacks programmable POCP and dual-phase mode. | Choose for AEC-Q100 compliance and simpler design; avoid when AMS transient response or dual-phase 12A capability is required. |
| TPS546D24RQFT | Single-channel 10A, 3V–16V input, PMBus interface, digital control; supports parallel operation but no native dual-output integration. | Used in programmable, telemetry-enabled systems; requires two ICs and external logic for true dual-rail independence. | Choose for digital monitoring/control and field updates; avoid when minimizing component count and footprint is critical. |
Compared with MPQ4485GQ-AEC1-P and TPS546D24RQFT, the MAX16712AWI+T uniquely combines dual-output integration, AMS-enhanced transient response, pin-strappable POCP/fSW, and dual-phase 12A capability in a 2.2mm × 3.5mm WLP - offering highest power density for space-constrained computing POLs without sacrificing configurability or protection robustness.

FAQ
What is the maximum supported output current for MAX16712AWI+T in dual-phase mode?
The MAX16712AWI+T supports up to 12A continuous output current in dual-phase mode when configured with SNSP2 tied to AVDD. This mode consolidates both channels into a single 12A output with interleaved 180° operation, validated across ambient temperatures up to +85°C with 200LFM airflow and no heatsink - per the Safe Operating Area curves in the datasheet.
How does the Advanced Modulation Scheme (AMS) in MAX16712AWI+T improve transient response?
The AMS in MAX16712AWI+T enables modulation at both leading and trailing edges of the switching cycle during large load transients, temporarily increasing or decreasing effective switching frequency. This extends closed-loop bandwidth to 140kHz (57° phase margin) and reduces output voltage deviation - demonstrated as <50mV droop during 1A–6A/μs steps - without requiring additional output capacitance.
Can MAX16712AWI+T operate with a pre-biased output voltage during startup?
Yes, MAX16712AWI+T supports smooth pre-biased startup: when the output voltage is already present (e.g., 0.5V), the device ramps up from that level without forcing reverse current through the inductor or causing output overshoot. This behavior is confirmed in Figure 13 of the datasheet and is essential for hot-swap and multi-rail sequencing applications.
What are the POCP threshold options for MAX16712AWI+T and how are they selected?
MAX16712AWI+T offers three selectable positive overcurrent protection (POCP) thresholds per output: 4.5A, 6A, or 9A. These are set independently for each channel using PGM1 and PGM2 pins, which accept three logic states (AGND, AVDD, or open). In dual-phase mode, only PGM1 configures the combined 12A POCP threshold; PGM2 is ignored.
Does MAX16712AWI+T integrate its own gate drivers and bias supply?
Yes, MAX16712AWI+T integrates high- and low-side MOSFET drivers and an internal 1.8V LDO. The VCC pin delivers 1.8V ±5% (80mA max) to power the gate drivers; AVDD (also 1.8V) is derived from VCC via an external 2.2Ω–4.7Ω resistor and powers the analog control circuitry - eliminating the need for external bias supplies.
