The LTC3805IMSE#TRPBF is a current mode controller designed for flyback DC/DC converters. It drives an N-channel MOSFET and is suitable for high input and output voltage applications. The operating frequency and slope compensation are programmable via external resistors, and it includes programmable overcurrent sensing for short-circuit protection.
Key electrical specifications include an input voltage range of 3.95V to 9.5V, an adjustable operating frequency from 70kHz to 700kHz, and a maximum duty cycle of 80%. It offers ±1.5% reference accuracy and low quiescent current, consuming only 360µA during normal operation and 40µA during micropower start-up.
This controller supports features like soft-start and has a RUN pin with precision threshold and adjustable hysteresis. It is synchronizable to an external clock. The device is available in a 10-MSOP-EP package and is designed for surface mount applications.
Typical applications include telecom power supplies and automotive power supplies. The LTC3805 is designed for excellent line and load transient response.
