Hot-selling and scarce LT1076CT Step-Down Switching Regulator TO220-5 spot stock

Product Descriptions

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 tappedinductor in the buck mode with output currents up to 10A. 

The LT1074 uses a true analog multiplier in the feedback loop. This  makes the device  respond  nearly  instantaneously to input voltage fluctuations and makes loop gain independent of input voltage.As a result,dynamic behavior of the regulator is significantly improved over previous designs.
