TPS65301QPWPRQ1

Overview

The TPS65301QPWPRQ1 is an automotive-grade PMIC featuring four outputs: one buck converter and three LDOs. It operates within a 5.6V to 40V input range, with the buck output providing up to 1.2A at 5.45V and an LDO delivering 350mA at 5V. The switching frequency ranges from 2MHz to 3MHz. Packaged in a 24-HTSSOP, it supports -40°C to 125°C operation and holds AEC-Q100 qualification.

Feature Summary

• Integrates one step-down converter and three low-dropout regulators for comprehensive power management
• Includes integrated voltage monitoring capabilities for system supervision
• Designed specifically for automotive applications with robust thermal performance

Applications

• Automotive infotainment systems requiring multi-rail power distribution
• Digital cockpit modules needing synchronized buck and linear regulation
• ADAS sensor interfaces demanding stable low-noise power supplies

Procurement Notes

Verify that the specific suffix matches the required package and temperature grade. Confirm AEC-Q100 compliance for your target automotive application. Check for any recent PCN updates regarding symbolization or manufacturing site changes. Ensure input voltage requirements align with your vehicle's electrical architecture before finalizing procurement.

Selection Notes

Select this component when a single solution is needed for both switching and linear regulation. The integrated buck handles higher current loads while LDOs provide clean power for sensitive analog circuits. Consider the 24-pin footprint constraints and verify that the 2MHz to 3MHz switching frequency fits your EMI budget without requiring extensive filtering.

Part Context

This device belongs to the TPS65301 family of multi-output power management ICs. It is designed to replace discrete regulator solutions in space-constrained automotive designs. The part integrates control logic and protection features typically found in separate components, simplifying the bill of materials.
