LTC3805 - Adjustable Frequency Current Mode Flyback DC/DC Controller

The LTC3805 is a current mode controller for yback 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. Softstart 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 360A of quiescent current during normal operation and only 40A 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.
