LM51561HQPWPRQ1

Overview

The LM51561HQPWPRQ1 is an automotive-grade DC-DC switching controller designed for boost, flyback, and SEPIC topologies. It supports a wide input voltage range from 2.97V to 60V and operates at switching frequencies between 100kHz and 2.2MHz. The device delivers up to 1.5A output current with a maximum duty cycle of 93%. It features integrated control characteristics including current limiting, enable functionality, frequency control, power good indication, and soft start. Qualified under AEC-Q100 standards, it functions reliably within an operating temperature range of -40°C to +125°C and is housed in a 14-HTSSOP package.

Feature Summary

Supports multiple non-isolated topologies including boost, flyback, and SEPIC configurations.
Integrated protection and control features such as current limiting, soft start, and power good signaling.
Automotive qualification compliant with AEC-Q100 standards for high reliability applications.

Applications

Automotive infotainment systems requiring wide input voltage handling
Industrial power supplies utilizing SEPIC or flyback architectures
Battery-powered equipment needing boost conversion capabilities

Procurement Notes

Verify the specific suffix PWPRQ1 confirms the HTSSOP-14 package and reel/cut-tape availability. Confirm AEC-Q100 qualification status matches project requirements. Check moisture sensitivity level (MSL 3) for proper storage and reflow soldering procedures. Ensure the supplier provides valid RoHS3 compliance documentation. Validate lead times against current production schedules.

Selection Notes

Select this component when designing circuits requiring flexible topology support beyond standard buck converters. Ideal for applications where input voltage may drop below or rise above output levels, necessitating SEPIC or boost functionality. Suitable for automotive environments demanding robust thermal performance and strict quality certifications. Consider the 2.2MHz maximum frequency for compact passive component sizing.

Part Context

Part of the LM5156xH-Q1 family of wide VIN automotive controllers. Designed to complement other Texas Instruments power management solutions for complex multi-rail automotive systems. Shares architectural similarities with non-automotive variants but includes enhanced testing and reliability specifications required for automotive deployment.
