LT1612EMS8#PBF

Overview

The LT1612EMS8#PBF is a monolithic high voltage isolated flyback converter manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5V to 36V and supports an output current of up to 1A. The device integrates a 600V power switch and features a fixed switching frequency of 100kHz. Designed for compact applications, it utilizes an 8-pin MSOP package. Key functional attributes include cycle-by-cycle current limiting, thermal shutdown protection, and soft-start capability to limit inrush current during startup.

Feature Summary

• Integrates a high-voltage 600V power switch for efficient isolated power conversion
• Provides comprehensive protection through integrated thermal shutdown and cycle-by-cycle current limiting
• Features a built-in soft-start mechanism to manage inrush current during initial power-up

Applications

• Isolated DC/DC converter modules
• General purpose isolated power supplies
• Battery chargers with isolation requirements

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the MSOP-8 package variant matches your PCB footprint requirements. Ensure the supplier provides valid manufacturer traceability documentation. Check for any regional distribution restrictions or obsolescence notices prior to finalizing procurement orders.

Selection Notes

Select this component for designs requiring a compact, single-stage isolated solution. It is suitable where space constraints limit the use of discrete transformer and controller combinations. Consider the 100kHz frequency for balancing efficiency and passive component size. Evaluate input voltage ranges against the specified 4.5V to 36V operational limits.

Part Context

This part belongs to the LT1612 family of high-voltage flyback converters. It serves as a complete power management solution for isolated applications. The series is designed to simplify board layout by integrating critical power stage components. It replaces traditional multi-component discrete designs in standard isolated topologies.
