LT3512MPMS#PBF

Overview

The LT3512MPMS#PBF is a monolithic high voltage isolated flyback converter manufactured by Analog Devices Inc. It integrates a 150V, 260mA power switch and operates from input voltages up to 100V. The device functions as a micropower no-opto-coupler flyback controller, utilizing primary-side regulation to eliminate the need for optocouplers and error amplifiers. Packaged in a 16-lead MSOP, it supports isolated DC/DC conversion with high efficiency and low standby current.

Feature Summary

Integrates a high-voltage power switch for compact isolated power solutions
Enables primary-side regulation without requiring optocouplers or feedback components
Designed for micropower applications with low quiescent current consumption

Applications

Isolated flyback converters for industrial instrumentation
Power supplies for medical equipment requiring galvanic isolation
Battery-operated devices needing efficient step-down conversion

Procurement Notes

Verify the exact suffix and tape-and-reel versus tube packaging options available from authorized distributors. Confirm RoHS compliance status and lead-free specifications against the latest manufacturer datasheet revision. Ensure the supplier provides traceability documentation for automotive or industrial grade parts if required by your design specifications.

Selection Notes

Select this component when designing isolated power stages that require minimal external component count and high reliability. It is suitable for applications where space constraints limit the use of traditional optocoupler-based feedback loops. Consider thermal performance and maximum load requirements relative to the integrated switch capabilities during circuit planning.

Part Context

This part belongs to the LT3512 family of isolated flyback converters. It shares functional similarities with other Linear Technology (now Analog Devices) no-opto controllers like the LT3573 and LT3837 series. These devices are designed to simplify isolated power supply designs by integrating control logic and power switching into a single monolithic package.
