Product details
Overview
TPS65320QPWPRQ1 from Texas Instruments is an automotive power-management IC combining a wide-input synchronous buck regulator with a low-dropout regulator. The device is designed for vehicle and industrial embedded modules that need an efficient pre-regulated rail plus a cleaner auxiliary rail in a rugged PowerPAD package.
As part of the TPS65320-Q1 family, TPS65320QPWPRQ1 supports automotive-grade power conversion, integrated buck and LDO regulation, enable and supervisory behavior, thermal PowerPAD packaging, and Q1-qualified supply use. For engineers reviewing the TPS65320QPWPRQ1 datasheet, TPS65320QPWPRQ1 pinout, TPS65320QPWPRQ1 application, or TPS65320QPWPRQ1 equivalent, this device is widely used in automotive body electronics, sensor modules, infotainment subsystems, industrial controllers, 12V battery-powered systems, and compact embedded power supplies.
Technical Context
In automotive modules, TPS65320QPWPRQ1 operates as a two-stage power-management device where the buck regulator efficiently steps down a vehicle or industrial input rail and the LDO regulator supplies a lower-noise secondary rail.
This buck-plus-LDO arrangement is useful when downstream microcontrollers, sensors, transceivers, or analog circuitry require both efficient conversion and cleaner local regulation. The PowerPAD package helps move heat into the PCB, which matters in sealed or high-temperature vehicle electronics.
TPS65320QPWPRQ1 is commonly used in Q1 automotive designs where input variation, thermal behavior, rail sequencing, and production traceability are more important than a consumer-grade single-output regulator.

Pinout & Package
The TPS65320QPWPRQ1 pinout includes buck input and switch pins, LDO input/output pins, enable and status/control pins, feedback or setting nodes, and PowerPAD ground connections.
For PCB design, the buck current loop should be compact, the PowerPAD should connect to thermal copper, and the LDO output capacitor should be placed close to the regulator output.
