DC DC Switching Controllers datasheet and documents for LTC3805MPMSE-5#TRPBF

LTC3805MPMSE-5#TRPBF

DC DC Switching Controllers Overview

The LTC3805MPMSE-5#TRPBF is an adjustable frequency current mode DC/DC controller designed for flyback, boost, and SEPIC converter applications. It operates within a switching frequency range of 70 kHz to 700 kHz and supports output voltages from 800 mV to 75 V. The device draws 360 µA of quiescent current during normal operation and features a 10-lead MSOP package with exposed pad. It functions reliably across a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

Supports flyback, boost, and SEPIC topologies via external N-channel MOSFET drive
Programmable switching frequency and slope compensation through external resistors
Integrated programmable overcurrent sensing for overload protection
Configurable soft-start with automatic restart capability

DC DC Switching Controllers Applications

Telecommunications isolated DC/DC converters
Industrial power supply designs
Battery-powered equipment requiring high efficiency

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the M-grade temperature rating aligns with system requirements. Check manufacturer documentation for lead-free status and RoHS compliance details before finalizing procurement specifications.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring flexible topology support including flyback and SEPIC configurations. Ensure external components are rated for the maximum operating voltage of 75 V. Verify that the required switching frequency falls within the 70 kHz to 700 kHz programmable range for optimal performance.

DC DC Switching Controllers Part Context

This part belongs to the LTC3805 family of high-voltage current mode controllers manufactured by Analog Devices. It shares core architecture with other variants in the series but differs in thermal grade and packaging configuration. The MP designation typically denotes military or extended industrial temperature ratings compared to standard commercial grades.
