LTC3805HMSE#TRPBF

DC DC Switching Controllers Overview

The LTC3805HMSE#TRPBF is an adjustable frequency current mode DC/DC controller designed for flyback, boost, and SEPIC converter applications. It drives an N-channel MOSFET with a switching frequency range of 70kHz to 700kHz. The device features programmable overcurrent sensing, external soft-start, and automatic restart capabilities. Quiescent current is 360μA during normal operation and 40μA in micropower startup. Output voltage accuracy is ±1.5%. It operates from a VCC/VDD supply of 3.95V to 9.5V and supports a maximum duty cycle of 80%. The component is housed in a 10-MSOP-EP package and functions within a junction temperature range of -40°C to 150°C.
