LT8357EMSE#TRPBF

Overview

The LT8357EMSE#TRPBF is a low quiescent current, 2MHz isolated SEPIC/Flyback DC/DC controller from Analog Devices. It supports wide input voltage ranges up to 60V and features a split gate drive for low-side N-channel MOSFETs. The device operates in current mode with adjustable frequency from 100kHz to 2MHz. It includes integrated protection features such as cycle-by-cycle current limit and thermal shutdown. The component is housed in a thermally enhanced MSOP-12 package suitable for space-constrained applications.

Feature Summary

Supports Boost, SEPIC, and Flyback converter topologies
Low quiescent current operation for efficiency optimization
Integrated split gate drive for external N-channel MOSFET control
Adjustable switching frequency from 100kHz to 2MHz

Applications

Isolated power supplies for industrial equipment
Battery-powered devices requiring high efficiency

Medical equipment power management

Procurement Notes

Verify the exact part number LT8357EMSE#TRPBF against official Analog Devices documentation to ensure correct suffix and tape & reel packaging configuration. Confirm RoHS compliance status and lead-free soldering specifications prior to procurement. Cross-reference the manufacturer's latest datasheet for any updates regarding recommended operating conditions or pinout configurations to avoid integration errors during design-in.

Selection Notes

Select this controller when an isolated topology is required with low standby power consumption. The wide input voltage range accommodates various battery and bus sources. Ensure the external MOSFET selection matches the 60V rating and current requirements. Consider the thermal performance of the MSOP-12 package relative to the expected power dissipation in the application environment.

Part Context

This component belongs to the LT8357 family of DC/DC controllers designed for high-efficiency isolated conversions. It complements other Analog Devices power management solutions by providing flexible topology options. The EMSE#TRPBF designation indicates the specific surface-mount package and tape-and-reel shipping format used for automated assembly processes.
