Product Overview

The LT1425CS#PBF is a monolithic high power Isolated Switching Regulator specifically designed for the isolated flyback topology. No third winding or opto-isolator is required, the integrated circuit senses the isolated output voltage directly from the primary side flyback waveform. A high current, high efficiency switch is included on the die along with all oscillator, control and protection circuitry. The LT1425 operates with input supply voltages from 3 to 20V and draws only 7mA quiescent current. It can deliver output power up to 6W with no external power devices. By utilizing current-mode switching techniques, it provides excellent AC and DC line regulation. It has a number of features not found on other switching regulator ICs. Its unique control circuitry can maintain regulation well into discontinuous mode in most applications. Optional load compensation circuitry allows for improved load regulation.
  • ±5% Accurate output voltage without user trims
  • Resistor programmable output voltage
  • Regulation maintained well into discontinuous mode (light load)
  • Optional load compensation
  • Easily synchronized to external clock
