LT3988EMSE#TRPBF

Overview

The LT3988EMSE#TRPBF is a dual-channel synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It features two independent buck regulators capable of delivering up to 1A output current each, with an adjustable output voltage range from 0.75V to 59.4V. The device operates with an input voltage range of 4.1V to 60V and supports switching frequencies between 250kHz and 2.15MHz. Packaged in a 16-lead MSOP with exposed pad (MSOP-EP), it is designed for high-efficiency power conversion in space-constrained applications.

Feature Summary

Dual-channel architecture providing two independent synchronous buck converters within a single compact package.
Integrated high-side N-channel MOSFETs enable efficient power conversion without requiring external Schottky diodes.
Wide input voltage range accommodates various supply sources, including battery and bus configurations.

Applications

Industrial control systems requiring multiple regulated voltage rails
Automotive electronics operating under wide input voltage conditions
Distributed power architectures in telecommunications infrastructure

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm that the component meets RoHS standards and complies with REACH regulations for environmental safety. Ensure compatibility with the intended PCB footprint and thermal management requirements for the MSOP-EP package.

Selection Notes

Select this component when dual isolated outputs are required from a single high-voltage source. Consider the maximum switching frequency limit and thermal dissipation capabilities of the 16-MSOP package. Evaluate the need for external compensation components based on the desired loop stability and transient response characteristics.

Part Context

This part belongs to the LT3988 family of dual synchronous buck converters. It shares functional similarities with other multi-channel PMICs but distinguishes itself through its specific 60V input rating and integrated synchronous rectification. It serves as a solution for applications needing compact, high-density power regulation.
