Product Summary

The LT1373CS8#TRPBF is a monolithic high frequency current mode switching regulator. It can be operated in all standard switching configurations including boost, buck, flyback, forward, inverting and Cuk. A 6A high efficiency switch is included on the die, along with all oscillator, control and protection circuitry. The LT1373CS8#TRPBF typically consumes only 4.5mA quiescent current and has higher efficiency than previous parts. High frequency switching allows for very small inductors to be used. The applications of the LT1373CS8#TRPBF include Boost Regulators, Laptop Computer Supplies, Multiple Output Flyback Supplies, Inverting Supplies.
