Product Overview

The LTC3805EDD-5#PBF is a current-mode DC/DC Controller designed to drive an N-channel MOSFET in flyback, boost and SEPIC converter applications. Operating frequency and slope compensation can be programmed by external resistors. Programmable overcurrent sensing protects the converter from overload and short-circuit conditions. Soft-start can be programmed using an external capacitor and the soft-start capacitor also programs an automatic restart feature. It 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, it can be powered from a high VIN through a resistor or it can be powered directly from a low impedance DC voltage from 4.7 to 8.8V.
  • VIN and VOUT Limited only by external components
  • 4.5V Undervoltage lockout threshold
  • Adjustable slope compensation
  • Adjustable overcurrent protection with automatic restart
  • Synchronizable to an external clock
  • ±1.5% Reference accuracy
  • Only 100mV Current sense voltage drop
  • RUN pin with precision threshold and adjustable hysteresis
  • Programmable soft-start with one external capacitor
  • 360µA Low quiescent current
