Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM5575QMH/NOPB

LM5575QMH/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM5575QMH/NOPB is an automotive-grade synchronous buck switching regulator from Texas Instruments, designed for high-voltage applications. It features a wide input voltage range of 6 V to 75 V and delivers a continuous output current of 1.5 A. The device supports adjustable output voltages from 1.225 V to 70 V with a fixed switching frequency range of 50 kHz to 500 kHz. It operates within a junction temperature range of -40°C to +150°C and is housed in a 16-pin HTSSOP package with exposed pad.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated synchronous rectification for improved efficiency in step-down conversion
Automotive qualification compliant with AEC-Q100 standards for reliability
Wide input voltage capability suitable for harsh automotive electrical environments
Adjustable switching frequency allows optimization for size and performance

Voltage Regulators - DC DC Switching Regulators Applications

Automotive infotainment systems requiring stable power regulation
Body control modules and lighting control units
High-voltage battery-powered subsystems in electric vehicles
Industrial DC-DC conversion where automotive grade reliability is required

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q100 automotive qualification status against the latest manufacturer datasheet. Ensure the 'MH' package code matches the required HTSSOP-16 footprint and thermal pad specifications for your PCB layout. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance as per current environmental regulations before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing for input voltages up to 75 V with a need for 1.5 A output current. It is appropriate for designs requiring automotive-grade reliability and extended temperature operation up to 150°C. Consider the 16-pin HTSSOP package constraints for thermal management and board space. Compare against non-automotive variants if cost is critical but automotive certification is not mandatory.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM5575 family of SIMPLE SWITCHER regulators, which are known for compact design and ease of use. The LM5575 series includes various packages and current ratings, such as the LM5575MHX for tape-and-reel packaging. The Q-series designation specifically denotes components manufactured to meet automotive quality and reliability standards, distinguishing them from standard commercial grade parts.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM5575MH/NOPB: Commercial grade equivalent without automotive qualification. LM5575MHX/NOPB: Tape and reel version of the commercial grade part. LM5576QMHX/NOPB: Higher current (3A) alternative in a different package.
