Product details
Overview
MAX16710AWA+ from Analog Devices is a fully integrated, fixed-frequency current-mode step-down DC-DC switching regulator delivering up to 10A output current, operating from 2.7V to 16V input, with adjustable 0.5V–5.8V output and configurable 500kHz–1.5MHz switching frequency. It features internal compensation, differential remote sensing, and advanced modulation (AMS) for improved load transient response - deployed in high-density point-of-load power delivery for servers and networking equipment.
For engineers reviewing the MAX16710AWA+ datasheet, MAX16710AWA+ pinout, MAX16710AWA+ application, or MAX16710AWA+ equivalent, key selection considerations include its 25-bump WLP package (2.52mm × 2.93mm), programmable overcurrent thresholds (11A/13A/15A), selectable DCM mode for light-load efficiency, and integrated 1.8V LDO for gate drive biasing - all critical for compact, thermally constrained data center power designs.
Technical Context
The MAX16710AWA+ implements fixed-frequency peak current-mode control with internal slope compensation and a 0.5V reference voltage. Its control loop includes an error amplifier, voltage-loop compensation network, and PWM modulator synchronized to an AMS-generated clock that enables leading- and trailing-edge modulation during transients.
Three programming pins (PGM0, PGM1, PGM2) configure switching frequency (500kHz–1.5MHz), POCP threshold (11A/13A/15A), DCM enable/disable, and predefined voltage-loop gain scenarios (A–F). Protection includes hiccup-mode positive/negative overcurrent (POCP/NOCP), output OVP/UVP, VDDH UVLO/OVLO, and OTP at 155°C with 20°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 10A continuous - supports high-current PoL rails without external MOSFETs or controllers. |
| Input Voltage Range | 2.7V to 16V - compatible with 3.3V, 5V, 12V intermediate bus architectures. |
| Output Voltage Range | 0.5V to 5.8V - covers core logic, I/O, and memory supply requirements via resistor divider. |
| Switching Frequency | 500kHz to 1.5MHz - selectable for size-efficiency trade-off; higher frequencies reduce inductor/capacitor footprint. |
| Peak Efficiency | 93.1% at 12VIN/1.8VOUT/500kHz - enables high thermal density in confined PCB areas. |

| Package | 25-bump wafer-level package (WLP), 2.52mm × 2.93mm - ultra-compact footprint for space-constrained modules. |
Pinout & Package
MAX16710AWA+ uses a 25-bump wafer-level package (WLP) with 2.52mm × 2.93mm footprint and 0.4mm pitch. The package supports −40°C to +125°C junction temperature operation and requires JEDEC-compliant reflow per RoHS lead-free profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | PGM0 | Resistor-strapped input selecting switching frequency (32 codes) and predefined control loop scenario (A–F). |
| B1 | AVDD | 1.8V analog supply rail; requires 2.2Ω–4.7Ω resistor from VCC and ≥1μF decoupling to AGND. |
| C1 | AGND | Analog ground reference for feedback, sense, and internal circuitry - must be separated from PGND at single-point. |
| D1 | SNSP | Remote sense positive input - connects directly to load for accurate regulation under IR drop. |
| E1 | PGOOD | Open-drain power-good flag - pulled low during faults (OVP, UVLO, OTP, OC) or soft-start. |
| A2 | VCC | Internal 1.8V LDO output powering gate drivers; requires ≥4.7μF ceramic capacitor to PGND. |
| B2 | PGM1 | 3-level strap pin selecting POCP threshold (11A/13A/15A) and DCM enable/disable. |
| C2 | PGM2 | 3-level strap pin co-defining POCP level and DCM mode with PGM1. |

| E2 | EN | Active-high enable with 250μs rising delay; supports sequencing and prebiased startup. |
| A3 | BST | Bootstrap node for high-side driver; requires 0.47μF ceramic capacitor to LX. |
| B3–E3 | VDDH | Main input supply (2.7V–16V); multiple pins reduce trace inductance and improve HF decoupling. |
| A4–E4 | LX | Switching node connecting to output inductor; high di/dt path requiring short, wide copper routing. |
| A4–E4 | PGND | Power ground return for LX, VDDH, and output capacitor - separate from AGND to minimize noise coupling. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ8633BGLE-Z | 12A rated, 2.8V–16V input, 500kHz–2MHz frequency, QFN-16 (4mm × 4mm), no AMS or differential sense. | Higher current but larger footprint; lacks AMS and remote sense - less suitable for tight transient specs or long PCB traces. | Prefer when >10A headroom is needed and layout allows larger package; avoid when differential sensing or sub-10μs load-step recovery is required. |
| TPS546D24RJNR | 10A, 3V–16V input, 400kHz–1.5MHz, 20-pin QFN (3.5mm × 4.5mm), PMBus interface, no internal LDO. | Digitally configurable via PMBus; requires external 3.3V bias for gate drive - adds complexity vs. MAX16710AWA+'s self-contained VCC. | Choose for systems needing telemetry, margining, or dynamic configuration; MAX16710AWA+ is simpler for fixed-function, analog-controlled PoL. |
Compared with MPQ8633BGLE-Z and TPS546D24RJNR, the MAX16710AWA+ delivers superior transient performance via AMS and eliminates external biasing with its integrated 1.8V VCC LDO - reducing component count and PCB area in space-constrained, analog-controlled server and networking power stages.

FAQ
What is the maximum output current capability of the MAX16710AWA+?
The MAX16710AWA+ delivers up to 10A of continuous output current under specified thermal conditions (TA = 55°C, 200LFM airflow). At TA = 85°C with no airflow, it sustains 10A output at 12VIN/1.8VOUT, validated per its Safe Operating Area curves. Peak current capability reaches 15A with appropriate POCP configuration and thermal design.
Does the MAX16710AWA+ require external compensation components?
No, the MAX16710AWA+ features internal compensation for its fixed-frequency current-mode control loop. This eliminates external compensation networks, simplifying design and improving consistency across temperature and manufacturing variance - confirmed in the device's Electrical Characteristics and Detailed Description sections.
How is the switching frequency configured on the MAX16710AWA+?
The MAX16710AWA+ switching frequency (500kHz–1.5MHz) is set via a resistor connected from PGM0 to AGND, selecting one of 32 discrete codes. Table 1 in the datasheet maps resistor values (e.g., 95.3Ω = 500kHz, 100kΩ = 1.5MHz) to frequency and control-loop scenario. PGM1/PGM2 do not affect frequency.
Can the MAX16710AWA+ operate with a prebiased output?
Yes, the MAX16710AWA+ supports smooth startup into a prebiased output. During enable, the IC monitors the output voltage and initiates soft-start only if below the target; if already biased, it transitions seamlessly to regulation without reverse current or overshoot - verified in the Startup and Shutdown Timing section.
What protections are built into the MAX16710AWA+?
The MAX16710AWA+ integrates positive/negative overcurrent protection (POCP/NOCP), output overvoltage/undervoltage protection (OVP/UVP), VDDH undervoltage/overvoltage lockout (UVLO/OVLO), and overtemperature protection (OTP at 155°C). All protections trigger hiccup-mode recovery with 20ms auto-restart, and status is reported via the open-drain PGOOD pin.
