LT1371 500kHz High Efficiency 3A Switching Regulator DESCRIPTION FEATURES n Faster Switching with Increased Efficiency The LT 1371 is a monolithic high frequency current mode n Uses Small Inductors: 4.7H switching regulator. It can be operated in all standard n All Surface Mount Components switching configurations including boost, buck, flyback, n Low Minimum Supply Voltage: 2.7V forward, inverting and Cuk. A 3A high efficiency switch n Quiescent Current: 4mA Typ is included on the die, along with all oscillator, control and n Current Limited Power Switch: 3A protection circuitry. n Regulates Positive or Negative Outputs The LT1371 typically consumes only 4mA quiescent n Shutdown Supply Current: 12A Typ current and has higher efficiency than previous parts. n Easy External Synchronization High frequency switching allows for very small inductors to be used. U APPLICATIONS New design techniques increase flexibility and maintain ease of use. Switching is easily synchronized to an exter- n Boost Regulators nal logic level source. A logic low on the Shutdown pin n Laptop Computer Supplies reduces supply current to 12A. Unique error amplifier n Multiple Output Flyback Supplies circuitry can regulate positive or negative output voltage n Inverting Supplies while maintaining simple frequency compensation tech- niques. Nonlinear error amplifier transconductance re- duces output overshoot on start-up or overload recovery. Oscillator frequency shifting protects external compo- nents during overload conditions. , LTC and LT are registered trademarks of Linear Technology Corporation.
