LT1370HVCR#PBF

LT1370 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. This device typically consumes only 4.5mA quiescent current and has higher efficiency than previous parts. Switching is easily synchronized to an external logic level source. Unique error amplifier circuitry can regulate positive or negative output voltage while maintaining simple frequency compensation techniques. Nonlinear error amplifier transconductance reduces output overshoot on start-up or overload recovery. 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.
