Product details
Overview
TPS62810QWRWYRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive synchronous step-down DC/DC converter delivering up to 4 A continuous output current, operating from 2.75 V to 6 V input, with adjustable output voltage (0.6 V–5.5 V), ±1% PWM output accuracy, and 15 µA typical quiescent current. It serves as the primary power supply for high-current rails in ADAS sensor fusion ECUs and infotainment head units.
For engineers reviewing the TPS62810QWRWYRQ1 datasheet, TPS62810QWRWYRQ1 pinout, TPS62810QWRWYRQ1 application, or TPS62810QWRWYRQ1 equivalent, key selection criteria include its 4 A output capability, 1.8–4 MHz adjustable switching frequency, wettable-flank VQFN-9 package, forced-PWM/PFM mode control, and integrated power-good with window comparator - all qualified for -40°C to +125°C ambient operation.
Technical Context
The TPS62810QWRWYRQ1 implements peak current mode control with internal compensation selectable via resistor on COMP/FSET, enabling stable regulation across 27–470 µF output capacitance ranges. Its dual-mode operation (PFM at light load, forced PWM at full load) maintains >90% efficiency from 1 mA to 4 A under 4.0 V input and 3.3 V output.
Functional safety support includes documentation for ISO 26262 ASIL-B system integration, precise ENABLE with user-defined UVLO and sequencing, active output discharge (50 Ω), and spread-spectrum clocking option. The device supports external synchronization (1.8–4 MHz) and 100% duty cycle operation for low-dropout scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 4 A continuous - supports high-power SoCs and FPGAs in automotive clusters without thermal derating at +125°C ambient. |
| Input Voltage Range | 2.75 V to 6 V - compatible with 3.3 V, 5 V, and 12 V (via pre-regulator) automotive battery systems including cold-crank transients. |
| Output Voltage Accuracy | ±1% in PWM mode - enables tight regulation for core logic supplies (e.g., 1.2 V ±12 mV) without post-regulation. |
| Quiescent Current | 15 µA typical - extends battery runtime in always-on telematics modules during vehicle sleep mode. |
| Switching Frequency | 1.8 MHz to 4 MHz adjustable - allows EMI optimization and small external component selection (e.g., 0.47 µH inductor). |
| Thermal Resistance | RθJA = 71.1°C/W - enables 4 A operation with minimal heatsinking on standard 2-layer PCBs using the RWY package. |

Pinout & Package
The TPS62810QWRWYRQ1 is housed in a 3.0 mm × 2.0 mm VQFN package with wettable flanks (RWY, 9-pin), optimized for automated optical inspection (AOI) and high-density automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 8) | Enable input | Logic-controlled startup with 1.06–1.15 V rising threshold; supports RC-based power-up delay and programmable undervoltage lockout. |
| FB (Pin 5) | Feedback input | 0.6 V reference node for external resistor divider; ±1% accuracy enables precise output voltage setting (e.g., 1.2 V, 3.3 V, 5.0 V). |
| GND (Pin 4) | Power ground | Primary return path for high-current switch node and control circuitry; requires low-inductance connection to minimize noise coupling. |
| MODE/SYNC (Pin 1) | Mode control / sync input | Selects PFM/PWM (low) or forced PWM (high); accepts 1.8–4 MHz external clock for EMI reduction and multi-rail synchronization. |
| COMP/FSET (Pin 7) | Compensation / frequency set | Resistor-to-GND sets both switching frequency (1.8–4 MHz) and internal loop compensation for 27–470 µF output capacitors. |
| PG (Pin 9) | Power-good open-drain output | Asserts high-Z when output is within ±5% of target; used for processor reset assertion or cascaded supply enable sequencing. |
| SS/TR (Pin 6) | Soft-start / tracking input | Capacitor-to-GND sets ramp time; also accepts external voltage for supply tracking (e.g., matching DDR memory rail sequencing). |
| SW (Pin 3) | Switch node | High-frequency switching point connecting internal high-side and low-side MOSFETs; requires tight layout with minimal loop area. |
| VIN (Pin 2) | Input supply | Accepts 2.75–6 V; must be decoupled with ≥5 µF ceramic capacitor placed adjacent to pin for transient suppression. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62903-Q1 | 3 A output, 1.8–6.5 V input, 12 µA IQ, integrated ferrite-bead filter for enhanced EMI performance. | Better suited for ultra-low-noise camera ISPs where conducted EMI must meet strict CISPR-25 limits without external filters. | Select TPS62903-Q1 when EMI filtering integration reduces board area and validation effort - not a pin-compatible replacement. |
| LM61480-Q1 | 8 A output, 3.0–36 V input, 15 µA IQ, adjustable current limit, no spread spectrum. | Targets higher-input-voltage domains (e.g., 12 V battery direct), requiring external pre-regulation for 6 V max input compatibility. | Choose LM61480-Q1 for scalability to 8 A loads or wider VIN range; requires layout revision due to different pinout and thermal pad. |
Compared with TPS62810QWRWYRQ1, TPS62903-Q1 offers lower EMI but reduced current capacity, while LM61480-Q1 delivers higher current and input range at the cost of larger footprint and no spread-spectrum capability - making TPS62810QWRWYRQ1 optimal for compact 4 A automotive rails with stringent thermal and EMI constraints.

FAQ
What is the maximum continuous output current of the TPS62810QWRWYRQ1?
The TPS62810QWRWYRQ1 delivers up to 4 A continuous output current at ambient temperatures up to +125°C, enabled by low RDS(on) high-side (37–60 mΩ) and low-side (15–35 mΩ) MOSFETs and optimized thermal design in the RWY package. This rating is validated per TI's recommended PCB layout and thermal conditions specified in the datasheet.
Does the TPS62810QWRWYRQ1 support external synchronization of its switching frequency?
Yes, the TPS62810QWRWYRQ1 supports external synchronization via the MODE/SYNC pin (Pin 1) across 1.8–4 MHz, provided a resistor is connected from COMP/FSET to GND. Synchronization occurs on the falling edge of the external clock relative to the SW pin rising edge, enabling phase-shifted operation for multi-converter systems to reduce input ripple.
What is the purpose of the SS/TR pin on the TPS62810QWRWYRQ1?
The SS/TR pin (Pin 6) serves dual functions: soft-start control (via capacitor-to-GND for 100–200 µs ramp time) and voltage tracking (via external reference input). In tracking mode, it enables precise sequencing of multiple rails - for example, aligning the TPS62810QWRWYRQ1 output with a companion 1.8 V supply to prevent latch-up in mixed-voltage FPGAs.
How does the TPS62810QWRWYRQ1 achieve high efficiency at light loads?
The TPS62810QWRWYRQ1 automatically transitions from fixed-frequency PWM to variable-frequency PFM mode below ~200 mA load, reducing switching losses and maintaining >85% efficiency down to 1 mA. This behavior is enabled by default when MODE/SYNC is pulled low, and is independent of external components.
Is the TPS62810QWRWYRQ1 qualified for automotive use?
Yes, the TPS62810QWRWYRQ1 is AEC-Q100 Grade 1 qualified (-40°C to +125°C ambient), with full functional safety documentation support for ISO 26262 ASIL-B system integration. It includes features critical for automotive reliability: wettable-flank packaging, 100% duty cycle operation, active output discharge, and robust ESD protection (±2 kV HBM).
