特点 Faster Switching with Increased Efficiency Uses Small Inductors: 4.7μH All Surface Mount ComponentsLow Minimum Supply Voltage: 2.7VQuiescent Current: 4mA TypCurrent Limited Power Switch: 3ARegulates Positive or Negative OutputsShutdown Supply Current: 12μA TypEasy External Synchronization典型应用典型应用描述描述 The LT?1371 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. The LT1371 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. 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.
