Description:
Adjustable Frequency Current Mode Flyback DC/DC Controller

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. Programmable overcurrent sensing protects the converter from short-circuits. Soft-start can be programmed using an external capacitor and the soft-start capacitor also programs an automatic restart feature. The LTC3805 provides ±1.5% output voltage accuracy  and consumes only 360µA of quiescent current during normal operation and only 40µA during micropower startup. Using a 9.5V internal shunt regulator, the LTC3805 can be powered from a high VIN through a resistor or it can be powered directly from a low impedance DC voltage of 9V or less. The LTC3805 is available in the 10-lead MSOP package and the 3mm × 3mm DFN package.
