LT8365JMSE#TRPBF

Overview

The LT8365JMSE#TRPBF is a synchronous step-up, SEPIC, and inverting switching regulator IC manufactured by Analog Devices Inc. It features a maximum input voltage of 60V and supports output voltages up to 150V via the internal switch node. The device delivers a switch current of 1.5A and operates with a programmable switching frequency ranging from 100kHz to 500kHz. It utilizes a 16-lead MSOP package with an exposed pad for thermal management. The component functions as a positive output transistor driver and maintains operation across a junction temperature range of -40°C to 150°C.

Feature Summary

• Integrated synchronous rectification for improved efficiency in boost and SEPIC configurations
• Supports high-voltage outputs up to 150V while accepting inputs up to 60V
• Programmable switching frequency allows optimization for external component size and performance
• Exposed pad package design facilitates effective thermal dissipation for high-current applications

Applications

• High-voltage boost converter designs for industrial systems
• SEPIC topology implementations for wide input voltage ranges
• Inverting power supply circuits requiring negative rail generation
• Battery-powered equipment needing extended operating life through efficient regulation

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the JMSE grade matches required thermal and electrical specifications against the official datasheet. Ensure compatibility with 16-MSOP footprint during PCB layout. Check RoHS compliance status if environmental regulations apply to your assembly process. Validate that the supplier provides genuine Analog Devices components to avoid counterfeit risks.

Selection Notes

Choose this component when designing circuits requiring high output voltages from moderate input sources. The 1.5A switch current capability suits medium-power applications. Consider the 16-MSOP package constraints for board space limitations. Evaluate the 100kHz to 500kHz frequency range against inductor selection requirements. Ensure thermal management strategies align with the exposed pad requirement for sustained operation at higher loads.

Part Context

This part belongs to the LT8365 family of high-voltage switching regulators. It shares core architecture with variants like the LT8365HMSE#TRPBF but differs in specified operating conditions or grading. The family targets applications demanding reliable power conversion in compact form factors. Analog Devices integrates synchronous control logic to minimize external component count while maintaining robust performance under varying load conditions.

Replacement Considerations

LT8365HMSE#TRPBF serves as a verified alternative within the same product family. Both parts share identical pinouts and functional capabilities. Verify temperature grades and specific electrical tolerances before substitution. Ensure packaging preferences match between TRPBF and any potential bulk alternatives.
