LT8365EMSE#PBF

Overview

The LT8365EMSE#PBF is a Boost/SEPIC switching regulator IC manufactured by Analog Devices Inc. It features a fixed output configuration with a transistor driver type, delivering a maximum switch current of 1.5A. The device supports an input voltage range from 2.8V to 60V and can generate output voltages up to 150V at the switch node. Operating frequencies are adjustable between 100kHz and 500kHz. It utilizes synchronous rectification for improved efficiency and is housed in a 16-MSOP package with an exposed pad (EP) for thermal management.

Feature Summary

• Supports Boost and SEPIC topologies for flexible input-to-output voltage conversion
• Integrates synchronous rectification to enhance power conversion efficiency
• Features an exposed pad package design to facilitate effective thermal dissipation
• Includes internal transistor driver capability for external component control

Applications

• Non-isolated DC/DC step-up converter designs
• Systems requiring wide input voltage ranges with high output voltage capabilities
• Industrial control circuits utilizing SEPIC topology for battery or variable source inputs

Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS 3 standards. Confirm the 16-MSOP-EP package variant matches the required footprint. Ensure the fixed output version aligns with circuit requirements, as adjustable variants exist within the same family. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a fixed output boost or SEPIC converter is needed with a 1.5A switch current limit. It is suitable for applications requiring input voltages up to 60V and output switch voltages up to 150V. Consider the 16-MSOP-EP package for space-constrained designs requiring robust thermal performance. Verify that the fixed output voltage meets system specifications, as trim pins are not available on this specific variant.

Part Context

This part belongs to the LT8365 family of high voltage boost and SEPIC regulators. It shares architectural similarities with the LT8364 but differs in output adjustability and current ratings. The LT8365 provides a fixed output solution, whereas other family members may offer programmable outputs. It is designed for industrial and automotive applications requiring reliable power conversion from varying input sources.

Replacement Considerations

LT8364EMSE#WPBF offers similar topology but with adjustable output and higher current rating.
