Product Overview

The LTC3805IMSE#PBF 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 controller 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.
  • Adjustable slope compensation
  • Adjustable overcurrent protection with automatic restart
  • Synchronizable to an external clock
  • ±1.5% Reference accuracy
  • Current mode operation for excellent line and load transient response
  • RUN pin with precision threshold and adjustable hysteresis
  • Programmable soft-start with one external capacitor
