LT1370IR Datasheet PDF - Linear Technology

DESCRIPTION

●The LT® 1370 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 LT1370 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.
