LTC3805 - Flyback DC/DC Controller

General Description

The LTC®3805 is a current mode controller for flyback DC/DC converters designed to drive an N-channel MOSFET in high input and output voltage converter applications.

Operating frequency and slope compensation can be programmed by external resistors.

Key Features
