Overview
The LT8365HMSE#PBF is a synchronous boost, SEPIC, and inverting DC/DC converter IC manufactured by Analog Devices Inc. It operates with an input voltage range of 2.8V to 60V and supports a maximum switch voltage of 150V. The device delivers a switch current of 1.5A and features a programmable switching frequency between 100kHz and 500kHz. It utilizes a 16-lead MSOP package with an exposed pad for thermal management. The component functions as a positive output transistor driver with a single output configuration.
Feature Summary
- Integrated synchronous rectification for improved efficiency in boost and SEPIC topologies
- High voltage switch rating supporting up to 150V drain-source voltage
- Low quiescent current operation for enhanced battery life in standby modes
- Exposed pad thermal enhancement package design for efficient heat dissipation
Applications
- Battery-powered instrumentation systems requiring high step-up ratios
- Industrial automation control circuits utilizing SEPIC configurations
- Communication equipment power supplies needing negative rail generation
- Portable devices requiring efficient voltage conversion from single-cell sources
Procurement Notes
Verify the specific suffix #PBF indicates lead-free tin termination compliant with RoHS standards. Confirm the package variant matches the 16-MSOP-EP specification for proper footprint alignment. Check manufacturer documentation for any recent Product Change Notifications regarding epoxy or marking updates. Ensure ordering quantities align with tube packaging constraints rather than reel formats.
Selection Notes
Select this component when input voltages exceed standard regulator limits but remain below 60V. Consider the 1.5A switch current capability against peak load requirements including ripple effects. Evaluate the thermal performance of the MSOP-EP package against expected ambient temperatures. Verify that the required switching frequency falls within the adjustable range of 100kHz to 500kHz for optimal filter component sizing.
Part Context
This part belongs to the LT8365 family of high voltage DC/DC converters designed for applications demanding wide input ranges and high output voltages. It shares architectural similarities with other members like the LT8365EMSE#PBF, differing primarily in temperature grade specifications. The series targets industrial and communication markets where reliability under varying thermal conditions is critical.
Replacement Considerations
LT8365EMSE#PBF serves as a verified alternative within the same product family, offering identical electrical functionality with a different operating temperature range specification.
