LT3511MPMS#PBF

Overview

The LT3511MPMS#PBF is a micropower isolated flyback converter manufactured by Analog Devices Inc. It integrates a high-voltage switch rated for 150V and 260mA, eliminating the need for external startup resistors. The device operates from an input voltage range of 4.7V to 100V. It features a fixed switching frequency of 100kHz and supports adjustable output voltages via external feedback components. The controller includes internal soft-start functionality and cycle-by-cycle current limiting to protect against overload conditions.

Feature Summary

Integrated high-voltage power switch eliminates external startup resistor requirements
Micropower quiescent current design optimizes efficiency in standby modes
Built-in soft-start limits inrush current during initial power-up sequences

Applications

Isolated power supplies for industrial instrumentation
Battery-powered systems requiring high step-down ratios
Telecommunications equipment with wide input voltage ranges

Procurement Notes

Verify the specific suffix MSMS indicates military-grade temperature ratings and enhanced reliability standards compared to commercial variants. Confirm RoHS compliance status through official datasheets as manufacturing processes may vary. Ensure compatibility with your PCB footprint specifications for the MSOP-10 package before finalizing procurement orders.

Selection Notes

Select this component when designing isolated converters requiring minimal external component count and high input voltage tolerance. The integrated switch simplifies layout and reduces bill of materials cost. Consider thermal management requirements due to the monolithic integration of the power stage within the small outline package.

Part Context

This part belongs to the LT3511 family of isolated flyback controllers designed for applications demanding high reliability and low standby power consumption. The MPMS variant specifically targets rugged environments with extended temperature capabilities. It serves as a compact solution for replacing discrete transformer driver circuits in space-constrained designs.
