LT3757AEDD#TRPBF

Overview

The LT3757AEDD#TRPBF is a wide input range, current mode DC/DC controller from Analog Devices Inc., designed for versatile power conversion topologies including Boost, Flyback, SEPIC, and Inverting configurations. It supports both positive and negative output voltages with a single output channel. The device operates within a switching frequency range of 100 kHz to 1 MHz and accepts an input voltage supply between 2.9 V and 40 V. Packaged in a compact 10-DFN (3x3) surface-mount format, it functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

Supports multiple converter topologies including Boost, Flyback, SEPIC, and Inverting circuits
Capable of generating both positive and negative output voltages
Features clock synchronization capability for system noise reduction
Includes integrated soft-start and frequency control functions

Applications

Industrial power supplies requiring isolated or non-isolated conversion
Automotive electronics systems operating under variable input conditions
Telecommunications infrastructure power management modules
Portable equipment utilizing battery-powered wide-range inputs

Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the 10-DFN footprint matches the PCB layout design specifications. Validate that the selected component meets all environmental operating temperature requirements for the intended application environment.

Selection Notes

Select this controller when designing systems requiring flexible topology support such as SEPIC or inverting architectures. Consider the wide input voltage range suitable for battery-driven applications. Evaluate the need for clock synchronization to minimize electromagnetic interference in dense layouts. Assess thermal performance requirements given the DFN package constraints and high-temperature operation capabilities.
