Product Summary

The LT1370IR 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 LT1370IR typically consumes only 4.5mA quiescent current and has higher efficiency than previous parts. The applications of the LT1370IR include: Boost Regulators, Laptop Computer Supplies, Multiple Output Flyback Supplies, Inverting Supplies.
