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

LTC3805MPMSE-5#PBF

DC DC Switching Controllers Overview

The LTC3805MPMSE-5#PBF is an adjustable frequency current mode DC/DC controller designed for flyback, boost, and SEPIC converter applications. It drives N-channel MOSFETs with a switching frequency range of 70 kHz to 700 kHz. The device supports output voltages from 800 mV to 75 V and delivers up to 2 A output current. Quiescent current is 360 μA during normal operation and 40 μA in micropower startup. It operates within a temperature range of -55°C to +125°C and is housed in a 10-lead MSOP package.

DC DC Switching Controllers Feature Summary

Supports flyback, boost, and SEPIC topologies with programmable frequency and slope compensation
Features ±1.5% output voltage accuracy and built-in overcurrent protection
Includes programmable soft-start with automatic restart capability
Operates from high VIN via internal shunt regulator or low impedance DC source

DC DC Switching Controllers Applications

High efficiency non-isolated SEPIC converters
Flyback power supplies requiring isolation
Boost converter designs with wide input ranges

DC DC Switching Controllers Procurement Notes

Verify the specific suffix MPMSE-5 against official Analog Devices documentation to confirm industrial temperature grade and pinout compatibility. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the #PBF designation matches RoHS compliance requirements for your assembly process.

DC DC Switching Controllers Selection Notes

Select this component when designing flyback, boost, or SEPIC converters requiring adjustable frequency control. It is suitable for applications needing precise output regulation and low quiescent current. Consider the 10-lead MSOP package constraints and thermal management requirements for the intended operating environment.

DC DC Switching Controllers Part Context

This part belongs to the LTC3805 series of current mode DC/DC controllers. It is manufactured by Analog Devices Inc. and is distinct from synchronous buck controllers like the LTC3824. The MP variant typically denotes an extended industrial temperature range compared to commercial versions.
