TPS65320QPWPRQ1

Overview

The TPS65320QPWPRQ1 is an automotive-grade PMIC featuring a dual-output topology with one buck converter and one LDO. It operates within a supply voltage range of 3.6V to 40V and supports switching frequencies from 100kHz to 2.5MHz. The buck output delivers up to 3.2A at voltages between 1.1V and 20V, while the LDO provides up to 280mA at 1.1V to 5.5V. Packaged in a 14-HTSSOP, it functions reliably across temperatures from -40°C to 125°C.

Feature Summary

• Integrates a high-current synchronous buck converter and a low-dropout linear regulator for efficient power distribution.
• Includes integrated voltage supervision monitors to ensure system reliability and fault detection.
• Features Eco-Mode technology to optimize efficiency under light-load conditions.
• Designed for automotive environments with AEC-Q100 qualification and extended temperature capability.

Applications

• Automotive infotainment systems requiring stable multi-rail power supplies
• Body control modules (BCM) managing various peripheral loads
• Gateway devices needing isolated or regulated power domains

Procurement Notes

Verify the specific suffix PWPRQ1 to confirm the HTSSOP package and automotive grade status. Confirm RoHS compliance and REACH status against current regulatory requirements. Check datasheet revisions for any symbolization updates that may affect pinout or electrical characteristics. Ensure the design accounts for the component's moisture sensitivity level during assembly.

Selection Notes

Select this component when a compact solution combining a high-current buck and an LDO is required for automotive applications. Consider the input voltage range compatibility with the vehicle's battery system. Evaluate thermal performance based on the expected load currents and ambient operating conditions. Verify that the integrated supervision features meet the safety requirements of the target application.

Part Context

This part belongs to the TPS653xx-Q1 family of power management ICs designed for automotive use. It shares functional similarities with the TPS65321-Q1 but differs in input voltage specifications and feature sets. The Q1 suffix denotes automotive qualification, ensuring reliability under harsh environmental conditions typical in vehicle electronics.

Replacement Considerations

The TPS65321QPWPRQ1 is a related variant within the same family. Verify input voltage ranges and specific feature availability before substitution, as differences exist between these models.
