LT1071HVIT

Conv DC-DC 3V to 60V Non-Inv/Inv/Step Up/Step Down Single-Out 1.244V to 60V 5.5A 100W 5Pin5+Tab TO-220

DESCRIPTION

The LT®1070/LT1071 are monolithic high power switching regulators. They can be operated in all standard switching configurations including buck, boost, flyback, for ward, 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 LT1070/LT1071 to be built in a standard

5-pin TO-3 or T0-220 power package. This makes it extremely easy to use and provides “bust proof” operation similar to that obtained with 3-pin linear regulators.
