The LT®1372/LT1377 are monolithic high frequencyswitching regulators. They can be operated in all standardswitching configuraTIons including boost, buck, flyback,forward, inverTIng and “Cuk.” A 1.5A high efficiency switchis included on the die, along with all oscillator, control andprotecTIon circuitry. All funcTIons of the LT1372/LT1377are integrated into 8-pin SO/PDIP packages.The LT1372/LT1377 typically consumes only 4mA quiescentcurrent and has higher efficiency than previous parts.High frequency switching allows for very small inductorsto be used. All surface mount components consume lessthan 0.5 square inch of board space.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 transconductance reducesoutput overshoot on start-up or overload recovery.Oscillator frequency shifting protects external componentsduring overload conditions.
