LT3757HMSE#TRPBF

Overview

The LT3757HMSE#TRPBF is a wide input voltage, current mode DC/DC controller manufactured by Analog Devices Inc. It supports Boost, Flyback, SEPIC, and Inverting topologies with positive or negative outputs. The device operates within an input voltage range of 2.9V to 40V and features a programmable switching frequency from 100kHz to 1MHz, including external clock synchronization. It utilizes a 10-MSOP-EP package and is rated for a junction temperature range of -40°C to 150°C.

Feature Summary

Supports multiple converter topologies including Boost, Flyback, SEPIC, and Inverting configurations.
Features internal 7.2V LDO for driving external N-channel MOSFETs without sense resistors.
Includes comprehensive protection mechanisms such as output overvoltage, overcurrent, and frequency foldback.

Applications

Industrial power supply systems
Automotive electronics
Telecommunications base station power management

Procurement Notes

Verify the specific suffix 'H' indicates the extended high-temperature grade (-40°C to 150°C) compared to standard variants. Confirm the '#TRPBF' designation ensures lead-free packaging compliant with RoHS standards. Cross-reference the manufacturer part number against official Analog Devices documentation to ensure accurate component identification before procurement.

Selection Notes

Select this component when designing circuits requiring flexible topology options like SEPIC or inverting converters from a single controller. The H-grade rating is essential for applications operating in elevated thermal environments up to 150°C. Ensure the design accommodates the 10-MSOP-EP package requirements for adequate thermal dissipation during operation.

Part Context

This part belongs to the LT3757 family of DC/DC controllers originally developed by Linear Technology, now part of Analog Devices. The LT3757 series is designed for versatile power conversion needs, offering a balance of efficiency and configurability. The HMSE variant specifically targets industrial and automotive sectors requiring robust performance across wide temperature ranges.
