Product Overview
LT1425 is a monolithic high power switching regulator specifically designed for the isolated flyback topology. No “third winding” or opt 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. It can deliver output power upto 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. It is used in application such as isolated flyback switching regulators, Ethernet isolated 5V to –9V converters, medical instruments, isolated telecom supplies etc.
