LP873300RHDTQ1

Overview

The LP873300RHDTQ1 is an automotive-grade PMIC from the LP8733 series, featuring dual 3-A buck converters and a dual LDO in a VQFN-28 package. It operates with an input voltage range of 2.8 V to 5.5 V. The buck outputs provide adjustable voltages from 700 mV to 3.6 V at up to 3 A each. The LDO outputs support ranges from 0.8 V to 3.3 V at 300 mA. It meets AEC-Q100 standards for -40°C to +125°C operation.

Feature Summary

• Dual high-current synchronous buck converters integrated within a single automotive-grade package
• Integrated low-dropout linear regulators providing auxiliary power rails
• Designed specifically for automotive applications meeting AEC-Q100 qualification requirements

Applications

• Automotive infotainment systems
• Digital cockpit electronics
• Advanced driver assistance systems (ADAS) power distribution

Procurement Notes

Verify the specific suffix 'DT' indicates the tape-and-reel packaging configuration distinct from other variants. Confirm the device meets the required AEC-Q100 grade specifications for your target automotive application environment. Ensure compatibility with the 28-pin VQFN footprint during PCB layout.

Selection Notes

Select this component when dual independent 3-A buck rails are required alongside LDOs in an automotive context. Compare against the LP8732 series if lower current ratings suffice. Verify that the 2.8 V minimum input voltage aligns with the system's battery or rail characteristics.

Part Context

This part belongs to the LP8733 family of multi-output power management ICs designed for complex automotive loads. It consolidates multiple regulation stages into a compact form factor, reducing solution size compared to discrete implementations while maintaining automotive reliability standards.

Replacement Considerations

LP873300RHDRQ1 is a parameter-equivalent alternative available in different packaging.
