Product details
Overview
MAX16962RAUEA/V+T from Maxim Integrated is a 4A, 2.2MHz synchronous step-down DC-DC converter operating from 2.7V to 5.5V input and delivering 0.8V–3.6V adjustable output voltage with ±3.7%/+2.6% total output error over load, line, and temperature. It integrates low-RDS(ON) power switches, supports SKIP and forced-PWM modes, and features open-drain power-good output with 16ms delay-designed for automotive infotainment point-of-load regulation.
For engineers reviewing the MAX16962RAUEA/V+T datasheet, MAX16962RAUEA/V+T pinout, MAX16962RAUEA/V+T application, or MAX16962RAUEA/V+T equivalent, key selection criteria include its 4A continuous output capability, 2.2MHz fixed-frequency operation enabling all-ceramic designs, factory-programmable SYNC I/O, spread-spectrum option (disabled in this variant), and -40°C to +125°C automotive qualification.
Technical Context
The MAX16962RAUEA/V+T implements a current-mode synchronous buck architecture with dual LX outputs (LX1/LX2) paralleled for 4A delivery, integrated high-side and low-side MOSFETs (RDS(ON) = 34mΩ/25mΩ typ), and internal 800mV feedback reference. Its PWM pin selects between forced-PWM (fixed 2.2MHz) and SKIP mode (26µA quiescent current), while the SYNC pin is factory-configured as input only.
Thermal protection triggers at +165°C with 15°C hysteresis; overcurrent protection uses peak-current limiting with 5.2A–8.5A threshold. The device requires external resistive feedback (via OUTS pin) for adjustable output, includes 8ms soft-start, and delivers power-good assertion within ±8%/+10% output deviation with 16ms timeout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports wide automotive battery range including cold-crank conditions. |
| Output Current | 4A continuous - enables single-chip supply for high-power SoCs or FPGA core rails. |
| Switching Frequency | 2.2MHz (fixed) - allows use of small 0.47µH inductors and all-ceramic output capacitors. |
| Feedback Reference | 800mV - sets output via external resistor divider; enables precise 0.8V–3.6V adjustment. |
| Output Accuracy | ±3.7%/+2.6% over load/line/temp - ensures stable rail under dynamic automotive operating conditions. |
| Quiescent Current | 26µA in SKIP mode - minimizes standby power loss in always-on vehicle systems. |
| Shutdown Current | 1µA - enables deep sleep states without battery drain. |
| Thermal Shutdown | +165°C with 15°C hysteresis - protects against sustained overload or poor heatsinking. |
Pinout & Package
MAX16962RAUEA/V+T is packaged in a thermally enhanced 16-pin TSSOP-EP (U16E+3) with exposed pad (EP) for PCB-level thermal management. Pin count and layout match JEDEC MO-153, supporting standard reflow profiles and automotive-grade reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX1, LX2 | Switching Nodes | Paralleled high-current paths for 4A output; require low-inductance routing to minimize switching losses. |
| PGND1, PGND2 | Power Ground Returns | Separate ground returns for each switch node; must connect to large copper pour under EP for thermal and EMI control. |
| PV1, PV2, PV | Input Supply Inputs | Dedicated inputs for main power path (PV1/PV2) and bias supply (PV); each requires local ceramic decoupling (≥4.7µF / ≥1µF). |
| EN | Enable Control | Active-high logic input; 2.4V min high threshold ensures robust start-up in noisy automotive environments. |
| OUTS | Feedback Input | Connects to external resistor divider; sensitive analog node requiring noise isolation from LX and GND loops. |
| PG | Power-Good Output | Open-drain signal asserting after 16ms delay when VOUT is within ±8%/+10%; requires 20kΩ pull-up. |
| PWM | Mode Select | Forces fixed-frequency PWM (high) or light-load SKIP mode (low); critical for efficiency vs. transient response trade-off. |
| SYNC | Synchronization I/O | Factory-configured as input only (1.7–2.4MHz range); enables system-level clock alignment across multiple converters. |
| GND | Analog Ground | Reference for internal circuitry; must tie to clean ground plane separate from PGND return paths. |
| EP | Exposed Thermal Pad | Must be soldered to solid copper ground plane with multiple vias; primary thermal conduction path for 2W+ dissipation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4436AGL-A-Z | 4A, 2.2MHz, 2.7–6V input; fixed 3.3V output only; no SYNC I/O; 1.2µA shutdown current. | Not adjustable; lacks power-good delay and automotive temp grade (-40°C to +125°C not guaranteed). | Select when fixed 3.3V output suffices and SYNC synchronization is unnecessary. |
| TPS62933RGER | 4A, 2.2MHz, 3–18V input; 0.4–5.5V adjustable output; 1.8µA IQ; integrated compensation. | Wider input range suits 12V systems; higher max input limits use in non-automotive industrial apps. | Choose for 12V input compatibility or when integrated loop compensation simplifies design. |
Compared with MPQ4436AGL-A-Z and TPS62933RGER, the MAX16962RAUEA/V+T uniquely combines automotive qualification, adjustable output, SYNC input capability, and proven 4A performance in TSSOP-EP-making it optimal for cost-sensitive, space-constrained infotainment power rails where system-level timing coordination matters.

FAQ
What is the maximum continuous output current of the MAX16962RAUEA/V+T?
The MAX16962RAUEA/V+T delivers up to 4A continuous output current when both LX1 and LX2 are paralleled, as confirmed in the Electrical Characteristics table under "Maximum Output Current" (IOUT = 4.4A typical). This rating holds across the full -40°C to +125°C operating temperature range with appropriate PCB thermal design using the exposed pad.
Does the MAX16962RAUEA/V+T support adjustable output voltage?
Yes, the MAX16962RAUEA/V+T supports adjustable output voltage from 0.8V to 3.6V using an external resistive divider connected to the OUTS pin. Its FB regulation voltage is fixed at 800mV, and the Selector Guide confirms the "RAUE" suffix denotes external adjustability-unlike factory-preset variants such as "RATE".
What is the function of the SYNC pin on the MAX16962RAUEA/V+T?
The SYNC pin on the MAX16962RAUEA/V+T is factory-programmed as an input-only port accepting external clock signals from 1.7MHz to 2.4MHz. This allows synchronization of multiple MAX16962RAUEA/V+T devices or other converters in the system to reduce beat frequencies and radiated EMI-critical in dense automotive PCB layouts.
How does the MAX16962RAUEA/V+T handle thermal overload?
The MAX16962RAUEA/V+T incorporates thermal shutdown that activates at +165°C junction temperature with 15°C hysteresis. When triggered, the internal bias regulator and step-down controller disable until the die cools below +150°C, preventing permanent damage during sustained overload or inadequate heatsinking-verified in the Absolute Maximum Ratings and Thermal Overload sections.
What package type is used for the MAX16962RAUEA/V+T?
The MAX16962RAUEA/V+T uses a 16-pin TSSOP-EP (exposed pad) package, identified as U16E+3 in Maxim's package documentation. This thermally enhanced package features an exposed thermal pad (EP) that must be soldered to a large contiguous copper ground plane with multiple vias for effective heat dissipation in automotive applications.
