The CS5150 is a 4-bit synchronous dual 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 100ns response time to load transients. The CS5150 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 CS5150 is specifically designed to power PentiumâPro processors and other high performance core logic. It includes the following features: on board, 4-bit DAC, short circuit protection, 1.0% output tolerance, VCCmonitor, and programmable soft start capability. The CS5150 is upward compatible with the 5-bit CS5155, allowing the mother board designer the capability of using either the CS5150 or the CS5155 with no change in layout. The CS5150 is available in 16 pin surface mount and DIP packages.
