LT3512IMS#PBF

Overview

The LT3512IMS#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 isolated flyback controller without requiring an opto-coupler, utilizing primary-side regulation for simplified design. It is housed in a 16-lead MSOP package with exposed pad.

Feature Summary

Integrates a high-voltage power switch rated for 150V breakdown
Eliminates the need for opto-couplers through primary-side regulation
Designed for micropower isolated flyback applications
Supports wide input voltage ranges up to 100V

Applications

Isolated DC/DC conversion for industrial sensors
Power supplies for communication equipment
Battery chargers requiring galvanic isolation
Medical instrumentation power stages

Procurement Notes

Verify the specific suffix IMS#PBF against the official Analog Devices datasheet to confirm the 16-lead MSOP package and lead-free RoHS compliance. Ensure the part number matches the exact pinout and thermal pad configuration required for your PCB layout. Cross-reference with Linear Technology legacy documentation if applicable, as Analog Devices acquired the product line.

Selection Notes

Select this component when designing isolated flyback converters that require minimal external components and do not need secondary-side feedback loops. It is suitable for low-power applications where efficiency at light loads is critical due to its micropower characteristics. Consider the 260mA switch current limit when sizing the transformer for the intended load requirements.

Part Context

The LT3512 belongs to the family of no-opto-coupler isolated flyback controllers from Analog Devices (formerly Linear Technology). These devices simplify power supply designs by removing the opto-isolator and associated bias winding, reducing component count and improving reliability. The IMS variant specifically denotes the MSOP package option within this product series.
