The CS5151H is a 4-bit nonsynchronous N-Channel buck controller. It is designed to provide unprecedented transient response for today’s demanding high-density, high-speed logic. The regulator operates using a proprietary control method, which allows a 100 ns response time to load transients. The CS5151H is designed to operate over a 4.25-20 V range (VCC) using 12 V to power the IC and 5.0 V or 12 V as the main supply for conversion. The CS5151H is specifically designed to power Pentium processors with MMX Technology and other high performance core logic. It includes features such as on board, 4-bit DAC, short circuit protection, 1.0% output tolerance, VCC monitor, and programmable Soft Start capability.
