LT1371CR#PBF

LT1371 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. This device is typically consumes only 4mA quiescent current and has higher efficiency than previous parts. High frequency switching allows for very small inductors to be used. New design techniques increase flexibility and maintain ease of use. Switching is easily synchronized to an external logic level source. A logic low on the shutdown pin reduces supply current to 12µA. Oscillator frequency shifting protects external components during overload conditions. It is widely used in application such as boost regulators, laptop computer supplies, multiple output flyback supplies, inverting supplies etc.
