Product details
Overview
TPS62810MWRWYR from Texas Instruments is a 4-A, synchronous step-down DC/DC converter with extended temperature operation (–55°C to +150°C), adjustable switching frequency (1.8 MHz to 4 MHz), ±1% output voltage accuracy in PWM mode, and forced-PWM/PFM operational flexibility. It delivers regulated power in high-reliability aerospace and defense systems requiring stable 0.6 V to 5.5 V output from a 2.75 V–6 V input.
For engineers reviewing the TPS62810MWRWYR datasheet, TPS62810MWRWYR pinout, TPS62810MWRWYR application, or TPS62810MWRWYR equivalent, key selection criteria include its wettable-flank VQFN-9 package, active output discharge, precise ENABLE with user-defined UVLO, power-good window comparator, and support for external synchronization across 1.8–4 MHz.
Technical Context
The TPS62810MWRWYR implements peak current mode control with internal loop compensation selectable via resistor on COMP/FSET, enabling stable operation with ceramic output capacitors as low as 27 µF (for VOUT ≥ 3.3 V). Its dual-mode operation-forced PWM or automatic PWM/PFM transition-maintains >90% efficiency from 1 mA to 4 A load at 3.3 V out.
Thermal performance is enabled by low RDS(ON) MOSFETs (37 mΩ high-side, 15 mΩ low-side at VIN ≥ 5 V), junction-to-board thermal resistance of 16.4°C/W, and integrated thermal shutdown at 170°C with 15°C hysteresis. The SS/TR pin supports programmable soft-start ramp time (100–200 µs) and voltage tracking for precise rail sequencing.

Pinout & Package
The TPS62810MWRWYR is housed in a 2-mm × 3-mm VQFN package with wettable flanks (RWY, 9-pin), optimized for automated optical inspection (AOI) and high-reliability solder joint formation in harsh-environment PCB assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Logic-controlled startup with precise 1.06–1.15 V rising threshold; supports RC-delayed power-up and custom UVLO via external divider. |
| FB | Voltage feedback input | Connects to resistive divider for adjustable output; 0.6 V reference enables 0.6–5.5 V regulation with ±1% accuracy. |
| GND | Power and signal ground | Common return path for input/output capacitors and IC core; requires low-inductance layout to minimize noise coupling. |
| MODE/SYNC | Mode control / external sync input | Pull low for PFM/PWM auto-switching; pull high for forced PWM; accepts 1.8–4 MHz external clock for multi-rail synchronization. |
| COMP/FSET | Compensation & frequency set | Resistor to GND selects both control-loop compensation (for 27–470 µF COUT) and switching frequency (1.8–4 MHz). |
| PG | Power-good open-drain output | Asserts high-Z when VOUT is within ±3% window; drives pull-up for system reset or monitoring logic. |
| SS/TR | Soft-start / tracking input | Capacitor sets 100–200 µs ramp time; also accepts external voltage for supply rail tracking during sequencing. |
| SW | Switch node | Connects to external inductor; carries high di/dt; requires tight layout and thermal relief for 4-A peak currents. |
| VIN | Input power supply | Accepts 2.75–6 V; requires local 5–10 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 |
|---|---|---|---|
| TPS62812MWRWYR | 2-A output current; identical pinout, package, and feature set except lower current limit and higher RDS(ON). | Suitable for lower-power subsystems (e.g., sensor interfaces, auxiliary MCUs) where 4-A headroom is unnecessary. | Select when full 4-A capability is not required and board space or cost optimization is prioritized. |
| LM61480RQR | 4-A rated, but only –40°C to +150°C operation; lacks extended –55°C start-up, spread spectrum, and wettable flanks. | Applicable in industrial motor drives or telecom infrastructure where military-grade cold start is not mandated. | Choose only if extended low-temperature operation and AOI-friendly packaging are not design requirements. |
Compared with TPS62810MWRWYR, the TPS62812MWRWYR offers pin-compatible 2-A operation with identical thermal and sequencing features, while the LM61480RQR provides comparable current but omits –55°C qualification and wettable flanks-making it unsuitable for certified aerospace or rail deployments.

FAQ
What is the minimum input voltage required for TPS62810MWRWYR to start up at –55°C?
The TPS62810MWRWYR supports start-up at –55°C with an input voltage of 2.75 V, as specified in the recommended operating conditions. This is enabled by its extended-temperature design and low-threshold enable circuitry, making it suitable for cold-soak scenarios in aircraft and rail systems where battery voltage may sag below nominal levels.
Does TPS62810MWRWYR support external clock synchronization, and what are the requirements?
Yes, TPS62810MWRWYR supports external synchronization via the MODE/SYNC pin across 1.8–4 MHz. To enable this, a resistor must be connected from COMP/FSET to GND to set the internal frequency near the external clock value; direct tie to VIN or GND disables synchronization. The device locks to the external clock within 50 µs on a falling edge.
How does the COMP/FSET pin affect both compensation and switching frequency in TPS62810MWRWYR?
The COMP/FSET pin simultaneously configures control-loop compensation (for output capacitance ranges: 27–470 µF) and switching frequency (1.8–4 MHz) via a single resistor to GND. Three compensation settings map to different RCF values and corresponding COUT minima-e.g., 10 kΩ yields comp setting 1 and 1.8 MHz, while 100 kΩ selects comp setting 3 and same frequency range but for larger capacitors.
What is the purpose of the SS/TR pin in TPS62810MWRWYR, and how is it used for rail sequencing?
The SS/TR pin serves dual functions: soft-start (via capacitor to GND for 100–200 µs ramp) and voltage tracking (by connecting to an external reference). For sequencing, it allows the TPS62810MWRWYR output to follow another supply's rise/fall profile, ensuring controlled power-up order between core and I/O rails in FPGAs or multi-voltage SoCs.
Is TPS62810MWRWYR qualified for functional safety applications, and what documentation is provided?
Yes, TPS62810MWRWYR is functional safety-capable. Texas Instruments provides dedicated documentation-including FIT rate calculations, failure mode effects analysis (FMEA), and safety manual-to aid system-level ISO 26262 or DO-254 certification. No additional hardware redundancy is required for basic safety integrity level (SIL/ASIL) implementation.
