Technical Attributes

DESCRIPTIONThe 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.FEATURES■ 5A Onboard Switch (LT1074)■ 100kHz Switching Frequency■ Greatly Improved Dynamic Behavior■ Available in Low Cost 5 and 7-Lead Packages■ Only 8.5mA Quiescent Current■ Programmable Current Limit■ Operates Up to 60V Input■ Micropower Shutdown Mode
