LT8357JMSE#TRPBF

Overview

The LT8357JMSE#TRPBF is a wide input range, current mode DC/DC controller from Analog Devices Inc. It supports boost, SEPIC, and flyback converter configurations with a 60V maximum input rating. The device operates at a switching frequency of 2MHz and features low quiescent current characteristics. Packaged in a 16-lead MSOP package, it is designed for applications requiring high efficiency and compact solution size.

Feature Summary

• Supports isolated SEPIC and flyback topologies
• Wide input voltage range up to 60V
• High switching frequency for small passive components
• Low quiescent current operation

Applications

• Industrial power supplies
• Battery-powered equipment
• Telecommunications systems
• Point-of-load converters

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the operating temperature grade matches the application requirements. Ensure compatibility with external MOSFETs and transformer specifications for the chosen topology. Check for valid RoHS compliance documentation if required by project standards.

Selection Notes

Select this component for designs requiring a wide input range and isolation in SEPIC or flyback architectures. Consider the 2MHz frequency for minimizing passive component size. Evaluate thermal performance within the MSOP package for the expected load conditions. Compare against alternatives if higher output voltages or different control modes are needed.

Part Context

This part belongs to the LT8357 family of DC/DC controllers. It shares core functionality with other variants like LT8357JMSE#PBF but differs in packaging and shipping format. The family targets efficient power conversion in space-constrained industrial and commercial applications.

Replacement Considerations

LT8357JMSE#PBF is a direct pin-compatible alternative with different packaging.
