Product details
Overview
TPS62813QWRWYRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive synchronous step-down DC/DC converter delivering up to 3 A continuous output current, operating from 2.75 V to 6 V input, with adjustable output voltage (0.6 V to 5.5 V), ±1% PWM-mode accuracy, and externally adjustable switching frequency from 1.8 MHz to 4 MHz. It serves as a primary power supply for infotainment processors and ADAS sensor fusion ECUs.
For engineers reviewing the TPS62813QWRWYRQ1 datasheet, TPS62813QWRWYRQ1 pinout, TPS62813QWRWYRQ1 application, or TPS62813QWRWYRQ1 equivalent, key selection criteria include its 3 A output capability, wettable-flank VQFN-9 package, active output discharge, precise enable with user-defined UVLO, and support for forced PWM or automatic PFM/PWM mode transition across load range.
Technical Context
The TPS62813QWRWYRQ1 implements peak current mode control with internal 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 MODE/SYNC pin supports both PFM/PWM auto-mode selection and external clock synchronization in 1.8–4 MHz range.
It integrates low-RDS(ON) MOSFETs (HS: 37–60 mΩ, LS: 15–35 mΩ at VIN ≥ 5 V), 15 µA typical quiescent current, 100% duty cycle capability, and a precision power-good output with window comparator (±5% threshold hysteresis). The SS/TR pin enables programmable soft-start or voltage tracking for rail sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 3 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 battery-backed automotive rails including cold-crank down to 2.75 V. |
| Output Voltage Accuracy | ±1% in PWM mode - ensures tight regulation for sensitive analog supplies and core voltages of vision processors. |
| Switching Frequency | 1.8 MHz to 4 MHz, adjustable via COMP/FSET resistor - enables EMI optimization and small external LC filter design. |
| Quiescent Current | 15 µA typical - minimizes standby power loss in always-on telematics and gateway modules. |
| Thermal Performance | RθJA = 71.1°C/W (VQFN-9) - validated for operation up to +150°C junction temperature per AEC-Q100 Grade 1. |

Pinout & Package
The TPS62813QWRWYRQ1 is housed in a 3 mm × 2 mm VQFN-9 package with wettable flanks (RWY), optimized for automated optical inspection (AOI) and high-reliability automotive solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 8) | Enable control input | Logic-compatible input with 1.06–1.15 V rising threshold; enables precise undervoltage lockout and power-rail sequencing via external resistor divider. |
| FB (Pin 5) | Voltage feedback node | Connects to resistive divider for adjustable output; internal 0.6 V reference enables 0.6–5.5 V regulation with ±1% accuracy in PWM mode. |
| GND (Pin 4) | Power and signal ground | Primary thermal and electrical return path; must be connected to low-impedance PCB plane for stability and thermal performance. |
| MODE/SYNC (Pin 1) | Mode selection / sync input | Pull low for PFM/PWM auto-mode; pull high for forced PWM; accepts external 1.8–4 MHz clock for multi-rail synchronization without additional components. |
| COMP/FSET (Pin 7) | Compensation & frequency set | Resistor to GND sets both control-loop compensation (for 27–470 µF COUT) and switching frequency (1.8–4 MHz); tied to GND/VIN fixes fSW at 2.25 MHz. |
| PG (Pin 9) | Power-good status output | Open-drain output asserting high when VOUT is within ±5% window of target; supports system reset and inter-rail coordination. |
| SS/TR (Pin 6) | Soft-start / tracking input | Capacitor to GND sets startup ramp time; can accept external voltage for output tracking during power-up or brownout recovery. |
| SW (Pin 3) | Switch node | Internal high-side/low-side MOSFET connection point; requires low-inductance layout and proper snubbing for EMI control. |
| VIN (Pin 2) | Input power supply | Accepts 2.75–6 V; requires local 5–10 µF ceramic input capacitor placed adjacent to pin for transient suppression and loop stability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Rated for –40°C to +125°C ambient operation with full electrical validation - meets automotive power supply reliability requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62812QWRWYRQ1 | 2 A output current; identical pinout, package, and feature set except reduced current limit and higher RDS(ON). | Suitable for lower-power clusters or single-core ADAS processors where 3 A headroom is unnecessary. | Select when total load current remains ≤2 A and thermal margin allows use of same PCB layout. |
| TPS62903RTERQ1 | 3 A, 2.7–6.5 V input, 15 µA IQ, but uses different 12-pin VQFN package and lacks spread spectrum; supports higher VIN max. | Better suited for next-gen platforms requiring wider input range or integrated LDO post-regulation. | Choose when upgrading beyond 6 V battery transients or needing dual-output capability not offered by TPS62813QWRWYRQ1. |
Compared with TPS62812QWRWYRQ1, the TPS62813QWRWYRQ1 delivers 50% more output current in identical footprint and thermal profile; compared with TPS62903RTERQ1, it offers wettable flanks, spread spectrum option, and tighter 2.75 V min VIN - making it preferred for cost-sensitive, high-volume automotive modules requiring AOI compatibility and EMI control.

FAQ
What is the maximum continuous output current of the TPS62813QWRWYRQ1?
The TPS62813QWRWYRQ1 delivers up to 3 A continuous output current across its full operating temperature range (–40°C to +125°C ambient), verified under worst-case conditions including 6 V input and high ambient temperature. This rating assumes proper PCB thermal design with adequate copper area and airflow per TI's layout guidelines in the datasheet.
Does the TPS62813QWRWYRQ1 support external clock synchronization?
Yes, the TPS62813QWRWYRQ1 supports external clock synchronization via the MODE/SYNC pin across 1.8 MHz to 4 MHz. Synchronization requires a resistor connected from COMP/FSET to GND - if COMP/FSET is tied directly to GND or VIN, external sync is disabled. The device locks to the external clock within 50 µs using a falling-edge–to–rising-edge alignment scheme.
What package type and dimensions does the TPS62813QWRWYRQ1 use?
The TPS62813QWRWYRQ1 uses a 3 mm × 2 mm VQFN-9 package with wettable flanks (RWY). It features nine terminals, including exposed thermal pad, and is designed for AOI-compatible reflow soldering in automotive manufacturing environments.
Can the TPS62813QWRWYRQ1 operate in 100% duty cycle mode?
Yes, the TPS62813QWRWYRQ1 supports 100% duty cycle operation, allowing VOUT to approach VIN minus dropout - critical for maintaining regulation during cold-crank events where input voltage drops near the output level. This behavior is enabled automatically when required by load and input conditions.
How is output voltage accuracy specified for the TPS62813QWRWYRQ1?
The TPS62813QWRWYRQ1 guarantees ±1% feedback voltage accuracy in PWM mode across –40°C to +125°C junction temperature and VIN ≥ VOUT + 1 V. In PFM mode, accuracy degrades to ±2% (for VOUT ≥ 1.5 V) due to light-load regulation trade-offs, as documented in Section 6.5 of the datasheet.
