LT3512IMS#TRPBF

Overview

The LT3512IMS#TRPBF is a micropower isolated flyback converter manufactured by Analog Devices Inc. It integrates a high-voltage switch and controller for offline applications, supporting input voltages up to 100V or 42V depending on the specific revision. The device features a 150V/260mA or 65V/1.2A internal switch. It operates with a fixed switching frequency and includes soft-start functionality to limit inrush current. The component is housed in an MSOP-10 package and is designed for high-efficiency power conversion in space-constrained designs.

Feature Summary

Integrated high-voltage switch eliminates external MOSFET requirements
Micropower operation reduces standby power consumption
No opto-coupler design simplifies transformer winding and assembly
Built-in soft-start limits input surge current during startup

Applications

Offline AC-DC adapters
Battery chargers
General-purpose isolated power supplies

Procurement Notes

Verify the specific suffix and revision code against the manufacturer's latest datasheet to confirm voltage ratings and switch capabilities, as variations exist within the LT3512 family. Ensure the ordering part number matches the required thermal performance and package type for your PCB layout. Cross-reference with official Analog Devices documentation to confirm RoHS compliance and material declarations before finalizing procurement.

Selection Notes

Select this component for applications requiring a compact, cost-effective isolated power solution without external control loops. Consider the integrated switch current limits when sizing the transformer. Evaluate the thermal dissipation capabilities of the MSOP-10 package relative to the expected load conditions. Verify that the input voltage range aligns with the specific variant's maximum rating.

Part Context

The LT3512 belongs to Analog Devices' family of isolated flyback converters designed for high-voltage offline applications. It replaces traditional discrete solutions by integrating the controller and power switch into a single IC. This integration reduces component count and board space, making it suitable for consumer electronics and industrial power supplies where efficiency and size are critical constraints.
