LT3511IMS#PBF

Overview

The LT3511IMS#PBF is a monolithic high voltage isolated flyback converter manufactured by Analog Devices Inc. It integrates a 150V, 260mA power switch and operates from an input voltage range of 4.5V to 100V. The device features a fixed switching frequency of 100kHz and includes internal soft-start functionality to limit inrush current during startup. It supports both continuous and discontinuous conduction modes for efficient power conversion in isolated applications.

Feature Summary

Integrates a high-voltage 150V power switch with a 260mA current capability
Eliminates the need for external start-up resistors through integrated bias circuitry
Includes internal soft-start mechanism to manage initial load stress

Applications

Isolated DC-DC converters requiring high input voltage ranges
Industrial control systems with wide input supply variations
Telecommunications equipment utilizing standard bus voltages

Procurement Notes

Verify the specific suffix IMS#PBF corresponds to the MSOP-16 package and lead-free RoHS compliance status. Confirm the operating temperature grade matches your design requirements, as industrial variants may differ from commercial grades. Ensure the ordering information aligns with the latest datasheet revision to avoid pinout or functional discrepancies.

Selection Notes

Select this component when a compact solution for high-voltage isolated power is required without external start-up components. It is suitable for designs needing a fixed 100kHz frequency to simplify magnetics selection. Consider thermal performance in the MSOP-16 package for higher power levels compared to larger packages.

Part Context

This part belongs to the LT3511 family of micropower isolated flyback converters. It is designed to replace discrete solutions by integrating the controller, oscillator, and power switch into a single small outline package. The family focuses on simplifying design for low-to-medium power isolated applications.
