Product Summary
The LT1170IQ 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 effi-ciency switch is included on the die along with all oscilla-tor, control and protection circuitry. Integration of all functions allows the LT1170IQ to be built in a standard 5-pin TO-3 or TO-220 power package as well as the 8-pin packages. The applications of the LT1170IQ include Logic Supply 5V at 10A, 5V Logic to ±15V Op Amp Supply, Battery Upconverter, Power Inverter (+ to-) or (- to +), Fully Floating Multiple Outputs.
