Product Summary
The LT1171CQ is a monolithic high power switching regulator. The device can be operated in all standard switching configurations including buck, boost, flyback, forward, inverting and Cuk. A high current, high efficiency switch is included on the die along with all oscillator, control and protection circuitry. Integration of all functions allows the LT1171CQ to be built in a standard 5-pin TO-3 or TO-220 power package as well as the 8-pin packages (LT1172). This makes it extremely easy to use and provides bust proof operation similar to that obtained with 3-pin linear regulators. The applications of the LT1171CQ include Logic Supply 5V at 10A, 5V Logic to ±15V Op Amp Supply, Battery Upconverter, Power Inverter (+ to –) or (– to +) and Fully Floating Multiple Outputs.
