Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM5576Q0MHX/NOPB

LM5576Q0MHX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM5576Q0MHX/NOPB is an automotive-grade, synchronous step-down switching regulator from Texas Instruments' SIMPLE SWITCHER family. It operates with an input voltage range of 6 V to 75 V and delivers a continuous output current of 3 A. The adjustable output voltage spans from 1.225 V to 70 V. The device supports a programmable switching frequency between 50 kHz and 500 kHz. It is housed in a 20-pin HTSSOP package and is qualified under the AEC-Q100 standard for automotive applications.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated synchronous rectification for high efficiency without external Schottky diodes
Automotive qualification compliant with AEC-Q100 standards
Programmable switching frequency allows optimization for size and performance
Built-in protection features including thermal shutdown and cycle-by-cycle current limiting

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power architectures in automotive systems
Point-of-load regulation for infotainment and instrument clusters
Industrial control system power supplies
High-voltage bus conversion in electric vehicle subsystems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Q0MHX' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and temperature grade. Ensure that the ordering part number matches the required automotive reliability specifications and pinout compatibility for your target PCB layout before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a high-input voltage buck converter is required for automotive environments. The 75 V input rating accommodates load dump conditions common in vehicle electrical systems. The 3 A output capability suits moderate-power loads, while the adjustable frequency feature enables designers to balance electromagnetic interference requirements against passive component size constraints effectively.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM5576-Q1 series within Texas Instruments' portfolio of high-voltage synchronous buck converters. It shares architectural similarities with the non-automotive LM5576 but includes enhanced testing and documentation to meet automotive quality standards. The family is designed to simplify power supply design by integrating the controller and power stage into a single compact package.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM5576MHX/NOPB: Non-automotive version with identical electrical specifications but lacking AEC-Q100 certification. LM5576QMHX/NOPB: Automotive version with different packaging (tube vs. reel) requiring re-verification of handling and assembly processes.
