Product details
Overview
TPS62875QWRZVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive synchronous step-down DC/DC converter delivering up to 20A output current, operating from 2.7V–6V input, with ±0.8% output voltage accuracy, differential remote sense, and I²C interface supporting up to 3.4MHz for real-time voltage/temperature monitoring in ADAS camera power rails.
For engineers reviewing the TPS62875QWRZVRQ1 datasheet, TPS62875QWRZVRQ1 pinout, TPS62875QWRZVRQ1 application, or TPS62875QWRZVRQ1 equivalent, key selection considerations include its 20A rated current, selectable 1.5/2.25/2.5/3MHz switching frequency via FSEL pin, forced-PWM/power-save mode control, and stacked operation capability for higher-current systems.
Technical Context
The TPS62875QWRZVRQ1 implements a fixed-frequency DCS-Control architecture optimized for fast transient response in automotive loads, with internal 2.6mΩ high-side and 1.5mΩ low-side MOSFETs enabling high efficiency at 125°C ambient. It supports differential remote sensing (VOSNS/GOSNS) to maintain ±0.8% DC accuracy at point-of-load under load-step conditions.
Its I²C interface provides register-based voltage adjustment, thermal warning (150°C), thermal shutdown (170°C), and power-good monitoring with window comparator; switching frequency is configurable via FSEL pin or external synchronization, and MODE/SYNC selects forced-PWM (low ripple) or power-save (high efficiency) operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 20A continuous - supports high-power ADAS SoCs and image sensors without external current sharing. |
| Input Voltage Range | 2.7V to 6V - compatible with 3.3V, 5V, and automotive 12V-derived intermediate rails. |
| Output Voltage Accuracy | ±0.8% - guaranteed across full temperature range (–40°C to +150°C junction) with remote sense compensation. |
| Switching Frequency | Selectable 1.5 / 2.25 / 2.5 / 3 MHz - enables compact magnetics and EMI optimization; supports external sync. |
| I²C Interface Speed | Up to 3.4 MHz (High-Speed mode) - allows rapid dynamic voltage scaling for performance-state transitions. |
| Thermal Protection | Thermal warning at 150°C and shutdown at 170°C - provides fail-safe operation in enclosed automotive ECUs. |
| Droop Compensation | Enabled with ±3.5 mV accuracy in forced-PWM - maintains precise voltage regulation during high di/dt load transients. |
Pinout & Package
RZV package: 24-pin WQFN-FCRLF (3.05mm × 4.05mm) with exposed thermal pad soldered to GND for optimal thermal resistance (RθJB = 6.5°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOSNS | Differential output voltage sense (+) | Connects to VOUT near load to enable closed-loop regulation at point-of-load; rejects PCB IR drop. |
| GOSNS | Differential output voltage sense (–) | Paired with VOSNS for Kelvin sensing; must be routed as matched pair to minimize noise coupling. |
| FSEL | Frequency select input | Resistor-to-GND/VIN sets switching frequency; enables 1.5/2.25/2.5/3MHz or external sync via MODE/SYNC. |
| VSEL | Startup voltage select input | Defines default VOUT at power-up (e.g., 0.75V, 0.80V, 0.875V) via resistor divider or direct tie-off. |
| MODE/SYNC | Operating mode control / sync input | Pull-low → power-save mode; pull-high → forced-PWM; also accepts external clock for phase-aligned stacking. |
| SYNC_OUT | Internal clock output | Drives MODE/SYNC of next device in daisy-chained stack; defines secondary role when pulled to GND via 47kΩ. |
| SDA / SCL | I²C bidirectional data / clock | Supports High-Speed mode (3.4MHz); requires pull-ups; SDA has 9mA sink capability for robust bus driving. |
| PG | Open-drain power-good output | Asserts high-Z when VOUT is within ±4% window; in stacked config, only primary device drives PG actively. |
Key Features
| Feature | Design Value |
|---|---|

| Configurable soft-start | Four ramp times (0.35–2.6ms) set via CONTROL2[1:0] register - prevents inrush current in multi-rail systems. |
| Spread spectrum clocking | Reduces peak EMI by ±10% frequency modulation at fSW/2048 rate - aids CISPR 25 Class 5 compliance in infotainment modules. |
| Functional safety documentation | TI provides FIT rate, failure modes, and diagnostic coverage data - supports ISO 26262 ASIL-B system integration. |

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 |
|---|---|---|---|
| TPS62876QWRZVRQ1 | 25A rated output current; higher ILIM (29–39A HS, 24.5–33A LS); identical pinout and feature set. | Suitable where future-proofing for higher SoC current or margin against aging derating is required. | Select when design targets >20A peak load or requires extended lifetime at 125°C ambient. |
| MPQ8645PGU-AEC1 | 20A rating, 2.7–6V input, but lacks I²C interface and differential remote sense; uses analog VID pins instead. | Applicable in cost-sensitive ADAS modules where dynamic voltage control and precision PoL regulation are not required. | Choose only if I²C telemetry, thermal warning, and ±0.8% remote-sense accuracy are unnecessary. |
Compared with TPS62875QWRZVRQ1, TPS62876QWRZVRQ1 offers higher current headroom with zero layout change, while MPQ8645PGU-AEC1 trades telemetry and precision for lower BOM count-making it viable only in static-voltage, non-safety-critical roles.

FAQ
What is the maximum output current capability of the TPS62875QWRZVRQ1?
The TPS62875QWRZVRQ1 is rated for 20A continuous output current under recommended operating conditions (TJ ≤ 150°C, proper PCB thermal design). Its internal 2.6mΩ high-side and 1.5mΩ low-side MOSFETs enable this rating at high ambient temperatures. Peak current capability is limited by ILIM thresholds: 24–32A for high-side FET and 20–29A for low-side FET, per datasheet Section 6.5.
Does the TPS62875QWRZVRQ1 support remote sensing, and how is it implemented?
Yes, the TPS62875QWRZVRQ1 supports true differential remote sensing using dedicated VOSNS (positive) and GOSNS (negative) pins. This configuration measures voltage directly at the load, compensating for PCB trace resistance and ensuring ±0.8% output voltage accuracy at point-of-load. The sensing lines must be routed as a matched pair away from noisy SW nodes to preserve measurement integrity.
How does the I²C interface on the TPS62875QWRZVRQ1 enhance system-level functionality?
The I²C interface on the TPS62875QWRZVRQ1 enables real-time monitoring and control-including dynamic VOUT adjustment, die temperature readback, thermal warning status, and power-good window validation-at speeds up to 3.4MHz. This allows host MCUs to implement adaptive power management, fault logging, and coordinated rail sequencing without additional ADCs or discrete monitors.
Can multiple TPS62875QWRZVRQ1 devices be operated in parallel, and what is required?
Yes, the TPS62875QWRZVRQ1 supports stacked operation for increased current or thermal spreading. Up to three devices can be daisy-chained using SYNC_OUT → MODE/SYNC connections, with shared COMP node and synchronized PG assertion. Secondary devices require 47kΩ pull-down on SYNC_OUT and grounded SDA/SCL; all EN pins must be tied together with appropriate drive strength.
What packaging and thermal characteristics define the TPS62875QWRZVRQ1's suitability for automotive environments?
The TPS62875QWRZVRQ1 uses the RZV 24-pin WQFN-FCRLF package (3.05mm × 4.05mm) with exposed thermal pad soldered to GND. It achieves RθJB = 6.5°C/W and RθJA = 28°C/W on 2-layer JEDEC boards, enabling reliable operation at 105°C ambient. Its AEC-Q100 Grade 1 qualification (–40°C to +125°C TA, –40°C to +150°C TJ) confirms automotive under-hood readiness.
