LP87702DRHBRQ1

Power Management - Specialized Overview

The LP87702DRHBRQ1 is an automotive-grade power management IC featuring two 3.5-A buck converters and a 5-V boost converter. It operates within a 2.8-V to 5.5-V input range, delivering up to 3.5 A per buck output with a maximum voltage of 3.36 V. The device utilizes a 4-MHz switching frequency and maintains a low quiescent current of 9 uA. Packaged in a 32-pin VQFN-EP, it supports operation from -40°C to +125°C and holds AEC-Q100 qualification for automotive reliability.

Power Management - Specialized Feature Summary

• Integrates dual high-current buck regulators and a dedicated boost stage for flexible power distribution
• Optimized for automotive environments with extended temperature ratings and robust qualification standards
• Supports compact designs through high-frequency switching and integrated thermal pad packaging

Power Management - Specialized Applications

• Automotive infotainment systems requiring multiple regulated voltage rails
• Digital cockpit displays and instrument clusters
• ADAS sensor power supply architectures

Power Management - Specialized Procurement Notes

Verify the complete part number including suffixes to ensure correct package type and tape/reel specifications. Confirm AEC-Q100 compliance requirements match your specific automotive application grade. Check moisture sensitivity levels and recommended soldering profiles prior to assembly. Ensure input voltage ranges align with vehicle battery conditions. Validate thermal performance expectations under maximum load conditions.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring dual independent buck outputs alongside a boost function. Consider the 3.5-A current capability for powering processors or display drivers. Evaluate the 4-MHz frequency for passive size reduction against efficiency trade-offs. Compare input voltage compatibility with standard automotive 12-V nominal systems. Assess thermal dissipation needs given the VQFN-EP package characteristics.
