LT3511MPMS#PBF

Overview

The LT3511MPMS#PBF is a monolithic high voltage isolated flyback converter manufactured by Linear Technology (Analog Devices). It integrates a 150V, 260mA power switch and requires no external startup resistor. The device operates from an input voltage range of 4.5V to 100V. It features a fixed switching frequency of 1MHz and includes programmable peak current limit for output current control. The component supports cycle-by-cycle current limiting and thermal shutdown protection.

Feature Summary

Integrated high voltage power switch eliminates external components
No external startup resistor required for operation
Programmable peak current limit controls maximum output current
Built-in thermal shutdown protects against overheating

Applications

Isolated DC/DC conversion in industrial equipment
Power supplies for instrumentation and measurement devices
Auxiliary power generation in telecom systems
Battery-powered applications requiring isolation

Procurement Notes

Verify the complete part number including suffixes such as #PBF for lead-free compliance and MS package code. Confirm manufacturer designation as Linear Technology or Analog Devices. Ensure the component matches the specified MPMS package variant. Cross-reference with official datasheets to validate electrical characteristics and pinout configuration before procurement.

Selection Notes

Select this component when an isolated flyback topology is required with minimal external parts count. The integrated switch simplifies design compared to discrete solutions. Consider the 260mA switch current limit for load requirements. The 1MHz frequency allows for smaller passive components. Verify input voltage compatibility within the 4.5V to 100V range.

Part Context

The LT3511 series belongs to Linear Technology's family of micropower isolated flyback converters. These devices are designed for applications requiring galvanic isolation with high efficiency. The MPMS variant indicates a specific miniaturized surface-mount package option. This series replaces traditional opto-coupler based designs by integrating control logic with the power stage.
