The LT®1370 is a monolithic high frequency current modeswitching regulator. It can be operated in all standardswitching configuraTIons including boost, buck, flyback,forward, inverTIng and “Cuk.” A 6A high efficiency switchis included on the die, along with all oscillator, control andprotecTIon circuitry.The LT1370 typically consumes only 4.5mA quiescentcurrent and has higher efficiency than previous parts.High frequency switching allows for very small inductorsto be used.New design techniques increase flexibility and maintainease of use. Switching is easily synchronized to an externallogic level source. A logic low on the Shutdown pinreduces supply current to 12mA. Unique error amplifiercircuitry can regulate posiTIve or negative output voltagewhile maintaining simple frequency compensation techniques.Nonlinear error amplifier transconductancereduces output overshoot on start-up or overload recovery.Oscillator frequency shifting protects external componentsduring overload conditions.
