The CS5156 is a 5-bit nonsynchronous N-Channel buck controller, which is specially designed to provide unprecedented transient response for today’s demanding high-density, high-speed logic. It operates using a proprietary control method, which allows a 100ns response time to load transients. The CS5156 is designed to operate over a 4.25-16V range (VCC) using 12V to power the IC and 5V as the main supply for conversion. The CS5156 is specifically designed to power Pentium® II processors and other high performance core logic. It includes the following features: on board, 5-bit DAC, short circuit protection, 1.0% output tolerance, VCC monitor, and programmable soft start capability. The CS5156 is backwards compatible with the 4-bit CS5151, allowing the mother board designer the capability of using either the CS5151 or the CS5156 with no change in layout. The CS5156 is available in 16 pin surface mount and DIP packages.
