Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM53635LQRNLRQ1

LM53635LQRNLRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LM53635LQRNLRQ1 is a synchronous step-down DC/DC converter from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It operates within an input voltage range of 3.9 V to 36 V and provides a fixed 3.3 V output at up to 3.5 A. The device features a switching frequency of 400 kHz and supports junction temperatures from -40°C to +150°C. Packaged in a 22-pin VQFN-HR (5x4 mm) housing, it includes shutdown functionality and low quiescent current characteristics suitable for power-sensitive systems.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated synchronous buck topology for high-efficiency power conversion
Automotive-grade reliability certified under AEC-Q100 standards
Extended thermal performance supporting operation up to 150°C junction temperature

Voltage Regulators - DC DC Switching Regulators Applications

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'L' indicates the fixed 3.3V output variant distinct from other output voltages in the series. Confirm package marking and date codes align with project requirements. Ensure compatibility with RoHS directives and REACH regulations before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V rail is required for automotive electronics. The 400kHz frequency offers a balance between component size and efficiency. Compare against adjustable variants if flexible output voltages are needed instead of the fixed configuration provided by this specific part number.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM53635-Q1 family of wide-input voltage synchronous buck converters. It shares the same core architecture and packaging as other members like the LM53635MQRNLRQ1 but differs in its internal feedback network setting the output voltage to 3.3V rather than adjustable or other fixed levels.
