Product Summary
The LT1371CR 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 3A high efficiency switch is included on the die, along with all oscillator, control and protection circuitry. The LT1371CR typically consumes only 4mA quiescent current and has higher efficiency than previous parts. High frequency switching allows for very small inductors to be used.
