Switching Regulator, LT1372CS8#PBF, Linear Technology
The LT1372CS8#PBF is a monolithic high-frequency switching regulator. It can be operated in all standard switching configurations including boost, buck, flyback, forward, inverting, and “Ćuk.” A 1.5A high-efficiency switch is included on the die, along with all oscillator, control, and protection circuitry. The LT1372CS8#PBF typically consumes only 4mA quiescent current and has higher efficiency than previous parts. High-frequency switching allows for very small inductors to be used. All surface-mount components consume less than 0.5 square inch of board space.
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. 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.
