LT1076HVIT

Conv DC-DC Single Step Down 8V to 60V 5Pin5+Tab TO-220

DESCRIPTION

The LT®1074 is a 5A LT1076 is rated at 2A monolithic bipolar switching regulator which requires only a few external parts for normal operation. The power switch, all oscillator and control circuitry, and all current limit components, are included on the chip. The topology is a classic positive “buck” configuration but several design innovations allow this device to be used as a positive-to-negative converter, a negative boost converter, and as a flyback converter. The switch output is specified to swing 40V below ground, allowing the LT1074 to drive a tapped inductor in the buck mode with output currents up to 10A.
