Product details
Overview
TPS62876QWRZVRQ1 from Texas Instruments is a 25A automotive-grade synchronous step-down DC/DC converter with I²C interface, differential remote sense, and fast transient response. It operates from 2.7V–6V input, delivers 0.4V–1.675V output with ±0.8% accuracy, and integrates 2.6mΩ/1.5mΩ MOSFETs for high-efficiency power delivery in ADAS camera modules.
For engineers reviewing the TPS62876QWRZVRQ1 datasheet, TPS62876QWRZVRQ1 pinout, TPS62876QWRZVRQ1 application, or TPS62876QWRZVRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to 125°C ambient), selectable 1.5/2.25/2.5/3MHz switching frequency, forced-PWM/power-save mode control, and stacked operation support for >25A current scaling.
Technical Context
The TPS62876QWRZVRQ1 implements a fixed-frequency DCS-Control topology optimized for rapid load-step response in safety-critical automotive systems. Its internal 2.6mΩ high-side and 1.5mΩ low-side MOSFETs enable 25A continuous output at high ambient temperatures, while differential remote sensing (VOSNS/GOSNS) maintains ±0.8% DC output voltage accuracy across the full 0.4V–1.675V range.
Control is implemented via dual-path configuration: analog pins (FSEL, VSEL, MODE/SYNC) set startup voltage, switching frequency, and operating mode; the I²C interface (up to 3.4MHz) enables dynamic voltage adjustment, real-time telemetry (temperature, voltage), and thermal warning signaling. Stacked operation uses SYNC_OUT/MODE/SYNC daisy-chaining with phase-shifted clocking (120° or 180°).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 25A continuous - supports high-power SoCs and image sensors in ADAS ECUs without external current sharing. |
| Input Voltage Range | 2.7V to 6V - compatible with 3.3V, 5V, and automotive battery-supplied rails including cold-crank conditions. |
| Output Voltage Range | 0.4V to 1.675V with 1.25mV/2.5mV/5mV steps - enables precise core voltage regulation for modern processors and ASICs. |
| Output Accuracy | ±0.8% - guaranteed over temperature and line/load, critical for functional safety compliance in ASIL-B/C systems. |
| Switching Frequency | 1.5 / 2.25 / 2.5 / 3 MHz - selectable via FSEL pin or external sync; higher frequencies reduce inductor size and improve transient response. |
| I²C Interface Speed | Up to 3.4 MHz (High-Speed mode) - enables rapid voltage updates and telemetry polling without CPU overhead. |
| Thermal Protection | 150°C thermal warning + 170°C shutdown with 20°C hysteresis - provides layered fault mitigation for sustained overload conditions. |
Pinout & Package
RZV package: 24-pin WQFN-FCRLF (3.05mm × 4.05mm) with exposed thermal pad soldered to GND for optimal thermal performance (RθJA = 28°C/W on EVM).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOSNS | Differential output voltage sense positive | Connects directly to point-of-load (POL) VOUT to enable closed-loop regulation at the load, minimizing IR drop errors. |
| GOSNS | Differential output voltage sense negative | Connects to POL ground return path; paired with VOSNS to reject common-mode noise and PCB trace resistance. |
| FSEL | Frequency select input | Resistor-to-GND/VIN sets nominal switching frequency (1.5/2.25/2.5/3 MHz) or enables external synchronization. |
| VSEL | Startup output voltage select input | Resistor divider or direct tie defines default VOUT at power-up (e.g., 0.75V, 0.80V, 0.875V) and I²C address (0x44–0x47). |
| MODE/SYNC | Operating mode control / sync input | Pull-low = Power-Save mode; pull-high = Forced-PWM; also accepts external clock for synchronized multi-rail designs. |
| SYNC_OUT | Internal clock output | Drives MODE/SYNC of next device in stacked configuration; 120° or 180° phase shift minimizes input ripple in parallel operation. |
| PG | Open-drain power-good output | Asserts high-impedance when VOUT is within ±4% window (96%–104%); tied together in stacked mode for system-level sequencing. |
| COMP | Loop compensation node | External RC network (R-C to AGND) sets Type-II/III compensation; shared across stacked devices for unified loop stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current automotive buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62875QWRZVRQ1 | 20A rated output; identical pinout, package, and feature set except lower current capability and reduced ILIM thresholds (24–32A vs. 29–39A). | Suitable for lower-power ADAS sensors or single-processor clusters where 25A margin is unnecessary. | Select when system peak current remains below 20A to reduce thermal design complexity and BOM cost. |
| MPQ8645PGU-AEC1 | 25A monolithic buck with 2.7V–16V input; no I²C interface; uses analog VID pins and lacks remote sense; 1.2MHz fixed frequency. | Applicable in non-telematics automotive modules where digital telemetry and fine-grained voltage control are not required. | Choose when I²C telemetry and differential sensing are not needed, and wider input range (up to 16V) is prioritized over programmability. |
Compared with TPS62875QWRZVRQ1, the TPS62876QWRZVRQ1 provides 5A higher continuous current and tighter droop compensation accuracy (±3mV vs. ±3.5mV), enabling more aggressive power delivery in thermally constrained ADAS housings; versus MPQ8645PGU-AEC1, it trades input voltage range for precision control, telemetry, and layout-optimized remote sensing.

FAQ
What is the maximum continuous output current of the TPS62876QWRZVRQ1?
The TPS62876QWRZVRQ1 delivers 25A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). Its internal 2.6mΩ/1.5mΩ MOSFETs and RθJA = 28°C/W (EVM) enable this rating at high ambient temperatures typical in engine bay or camera housing environments. Derating applies above 125°C junction temperature.
Does the TPS62876QWRZVRQ1 support remote voltage sensing?
Yes, the TPS62876QWRZVRQ1 supports true differential remote sensing via dedicated VOSNS and GOSNS pins. This architecture measures voltage directly at the load, compensating for PCB trace resistance and ensuring ±0.8% output accuracy at the point-of-load - critical for powering sensitive image sensors and processors in ADAS systems.
How is the switching frequency configured on the TPS62876QWRZVRQ1?
The TPS62876QWRZVRQ1 switching frequency is selected via the FSEL pin: resistor-to-GND or resistor-to-VIN sets 1.5MHz, 2.25MHz, 2.5MHz, or 3MHz. Alternatively, an external clock applied to the MODE/SYNC pin synchronizes switching across multiple rails. The device also supports spread-spectrum clocking to reduce EMI peaks.
Can multiple TPS62876QWRZVRQ1 devices be operated in parallel?
Yes, the TPS62876QWRZVRQ1 supports stacked operation using SYNC_OUT and MODE/SYNC pins to daisy-chain up to three devices. Phase shifts of 120° or 180° minimize input ripple, and shared COMP compensation ensures stable loop behavior. All devices must use identical FSEL and VSEL configurations for predictable current sharing.
What automotive qualification does the TPS62876QWRZVRQ1 meet?
The TPS62876QWRZVRQ1 is AEC-Q100 qualified for automotive applications (Grade 1: –40°C to 125°C ambient, –40°C to 150°C junction). It includes functional safety documentation to support ISO 26262 ASIL-B/C system development, along with thermal warning (150°C), thermal shutdown (170°C), and comprehensive fault reporting via I²C.
