Product details
Overview
TPS62877QWRZVRQ1 from Texas Instruments is a 30A 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 output voltage from 0.4V to 1.675V with ±0.8% accuracy, and integrates 2.6mΩ/1.5mΩ power MOSFETs for high-efficiency operation in ADAS camera and surround-view ECU power rails.
For engineers reviewing the TPS62877QWRZVRQ1 datasheet, TPS62877QWRZVRQ1 pinout, TPS62877QWRZVRQ1 application, or TPS62877QWRZVRQ1 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 configuration support for >30A output current scaling.
Technical Context
The TPS62877QWRZVRQ1 implements a fixed-frequency DCS-Control™ architecture optimized for sub-1µs load transient response in automotive safety-critical rails. Its dual-loop control supports both voltage-mode regulation via COMP pin compensation and droop-based current sharing in stacked configurations.
Differential remote sensing (VOSNS/GOSNS) enables precise point-of-load regulation under high-current conditions, while thermal pre-warning (150°C) and shutdown (170°C) thresholds ensure robust junction temperature management up to 150°C. The I²C interface supports real-time voltage monitoring, register-based configuration, and dynamic output adjustment at up to 3.4MHz clock rate.

Pinout & Package
RZV package: 24-pin WQFN-FCRLF (3.05mm × 4.05mm) with exposed thermal pad soldered to GND for optimal thermal performance (RθJB = 6.5°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOSNS | Differential output voltage sense (+) | Connects to point-of-load VOUT+ for precision regulation; rejects PCB trace IR drop. |
| GOSNS | Differential output ground sense (–) | Connects to point-of-load GND return path; completes Kelvin sensing loop with VOSNS. |
| SW | Power switch node | Drives external inductor; requires low-inductance layout due to high di/dt at 30A peak currents. |
| COMP | Control loop compensation input | External RC network sets bandwidth and phase margin; shared across stacked devices. |

| VSEL | Startup voltage select input | Defines initial VOUT at power-on (e.g., 0.75V/0.80V/0.875V); also sets I²C address (0x44–0x47). |
| MODE/SYNC | Operating mode control | Pull-low = Power-Save mode (light-load efficiency); pull-high = Forced-PWM (low ripple, fast transient). |
| PG | Open-drain power-good output | Signals valid VOUT within ±4% window; daisy-chained in stacked configurations for system-level sequencing. |

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 |
|---|---|---|---|
| TPS62876QWRZVRQ1 | 25A rated; identical pinout, package, and feature set except lower current limit and higher RDS(on). | Suitable for mid-tier ADAS ECUs with 20–25A peak load; lower thermal stress but reduced headroom for future SoC upgrades. | Select when system peak current is confirmed ≤25A and cost optimization is prioritized over scalability. |
| LM61480QRNXTQ1 | 16A rated; no I²C interface; uses current-mode control instead of DCS-Control™; lacks remote sense pins. | Applicable for non-DVFS, fixed-voltage rails where telemetry and dynamic scaling are unnecessary. | Choose only if I²C monitoring, point-of-load regulation, or >25A capability are not required - avoids over-specification. |
Compared with TPS62876QWRZVRQ1, the TPS62877QWRZVRQ1 provides 5A higher current headroom and tighter RDS(on) tolerance for thermally constrained layouts; versus LM61480QRNXTQ1, it adds critical automotive features including remote sensing, I²C telemetry, and stacked operation - essential for next-generation ADAS domain controllers.

FAQ
What is the maximum supported output current for TPS62877QWRZVRQ1?
The TPS62877QWRZVRQ1 is rated for 30A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). Its internal power MOSFETs (2.6mΩ HS / 1.5mΩ LS) and thermal design enable sustained 30A delivery even at 125°C ambient, with derating above that junction temperature per datasheet thermal metrics.
Does TPS62877QWRZVRQ1 support remote sensing, and how is it implemented?
Yes, the TPS62877QWRZVRQ1 supports true differential remote sensing using dedicated VOSNS (output voltage sense) and GOSNS (output ground sense) pins. This Kelvin connection measures voltage directly at the load, rejecting PCB trace resistance effects and enabling ±0.8% regulation accuracy across the full 0.4V–1.675V output range - critical for low-voltage, high-current SoC rails.
Can multiple TPS62877QWRZVRQ1 devices be operated in parallel, and what is required?
Yes, the TPS62877QWRZVRQ1 supports stacked operation for increased output current or thermal spreading. Up to three devices can be synchronized using SYNC_OUT → MODE/SYNC daisy-chaining, with shared COMP and PG nodes. External resistors define primary/secondary roles, and droop compensation ensures balanced current sharing without external current-sense amplifiers.
What I²C speeds does TPS62877QWRZVRQ1 support, and what are the implications?
The TPS62877QWRZVRQ1 supports I²C up to 3.4MHz (High-Speed mode), enabling sub-100µs register reads/writes for dynamic voltage scaling during processor DVFS. This speed requires ≤100pF bus capacitance and appropriate pull-up strength; slower modes (400kHz Fast Mode, 100kHz Standard Mode) are also supported for compatibility with legacy microcontrollers.
How is thermal protection implemented in TPS62877QWRZVRQ1?
The TPS62877QWRZVRQ1 includes two independent thermal protections: a thermal warning flag triggered at 150°C junction temperature (allowing firmware-initiated throttling), and hard thermal shutdown at 170°C with 20°C hysteresis. Both thresholds are specified across the full –40°C to +150°C junction range and are monitored internally without external components.
