Voltage Regulators - DC DC Switching Regulators datasheet and documents for LMQ66410MA5RXBRQ1

LMQ66410MA5RXBRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LMQ66410MA5RXBRQ1 is an automotive-grade synchronous step-down converter from Texas Instruments, designed for low electromagnetic interference applications. It features a wide input voltage range of 3 V to 36 V and delivers a fixed 5 V output at up to 1 A. The device operates with a switching frequency of 400 kHz and maintains a typical quiescent current of 2 uA. It supports junction temperatures from -40°C to +150°C and utilizes a VQFN-FCRLF-EP-14 package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Optimized for low electromagnetic interference in automotive environments
Supports high-voltage transients up to 42 V for load dump protection
Enables ultra-low standby power consumption via automatic mode operation
