LT3759HMSE#TRPBF

Overview

The LT3759HMSE#TRPBF is a DC-DC switching controller from Analog Devices Inc., designed for versatile power conversion topologies including boost, flyback, and SEPIC configurations. It supports positive or negative output voltages and is capable of providing isolated outputs. The device operates with a supply voltage range of 1.6V to 42V and features an adjustable switching frequency between 100kHz and 1MHz. Packaged in a 12-MSOP-EP surface-mount format, it includes control features such as enable, frequency control, power good indication, and soft start functionality.

Feature Summary

• Supports multiple converter topologies including boost, flyback, and SEPIC for flexible system design
• Capable of generating positive, negative, or isolated output voltages
• Integrates clock synchronization capability for noise reduction and multi-phase operation
• Includes built-in soft start and power good monitoring for reliable system startup

Applications

• Industrial power supplies requiring wide input ranges
• Battery-powered equipment utilizing boost or SEPIC architectures
• LED lighting drivers needing isolated or negative rail generation
• Telecommunications infrastructure power management modules

Procurement Notes

Verify the specific suffix #TRPBF confirms tape and reel packaging when ordering. Ensure the HMSE variant matches the required temperature and performance specifications compared to other family members. Confirm that the 12-MSOP-EP footprint aligns with the PCB layout requirements. Check for any recent product change notifications regarding epoxy or marking changes before finalizing procurement plans.

Selection Notes

Select this component when a single controller must support diverse topologies like boost, flyback, or SEPIC within one design platform. The wide input voltage range suits applications with varying source conditions. Consider the exposed pad package for thermal management needs. Evaluate the need for clock synchronization if operating in noisy environments or parallel configurations. Verify that external MOSFETs and passive components are rated for the expected peak currents and voltages.

Part Context

This part belongs to the LT3759 series of wide input range DC-DC controllers. It shares functional similarities with other parts in the family but differs in package type and specific electrical characteristics. The LT3759 series is designed to replace discrete solutions by integrating control logic into a compact IC. It complements other Linear Technology power management devices by offering flexibility in topology selection without changing the core control architecture.
