LT3757AMPMSE#PBF

Overview

The LT3757AMPMSE#PBF is a monolithic, wide input range, current mode DC/DC controller manufactured by Analog Devices Inc. It supports Boost, Flyback, SEPIC, and Inverting topologies to generate positive or negative output voltages. The device operates with a switching frequency ranging from 100 kHz to 1 MHz and accepts a supply voltage between 2.9V and 40V. Packaged in a 10-MSOP-EP surface-mount format, it features clock synchronization, soft start, and enable functions. The component is rated for an operating temperature range of -40°C to +125°C.

Feature Summary

Supports multiple converter topologies including Boost, Flyback, SEPIC, and Inverting configurations.
Capable of generating both positive and negative output voltages from a single controller.
Features internal clock synchronization and programmable soft-start functionality.
Operates over a wide input voltage range suitable for diverse power applications.

Applications

Industrial power supplies requiring isolated or non-isolated outputs
Telecommunications equipment with variable input voltage ranges
Automotive electronics systems utilizing boost or flyback architectures
Battery-powered devices needing step-up or inverting regulation

Procurement Notes

Verify the specific suffix PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the AMPMSE package variant matches the required footprint and thermal pad specifications. Ensure the A-grade temperature rating aligns with the operational environment requirements. Cross-reference the manufacturer's latest datasheet for any pinout or electrical characteristic updates.

Selection Notes

Select this controller when a wide input voltage range and flexible topology support are required. It is suitable for designs needing precise current mode control without external compensation complexity. Consider the 10-MSOP-EP package for thermal performance and space constraints. Evaluate the need for clock synchronization if multiple converters operate in proximity.

Part Context

The LT3757 series belongs to Analog Devices' portfolio of high-performance DC/DC controllers. It is part of the broader LT3757/LT3757A family, which includes variants with different temperature grades and packaging options. This component complements other power management ICs by providing versatile control solutions for complex power conversion needs.
