CS5155 General Description

The CS5155 is a 5-bit synchronous dual N-Channel buck controller. It is designed to provide unprecedented transient response for todayÕs demanding high-density, high-speed logic. The regulator operates using a proprietary control method, which allows a 100ns response time to load transients. The CS5155 is designed to operate over a 4.25-14V range (V_CC) using 12V to power the IC and 5V as the main supply for conversion. The CS5155 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, V_CC monitor, and programmable soft start capability. The CS5155 is backwards compatible with the 4 bit CS-5150, allowing the mother board designer the capability of using either the CS-5150 or the CS5155 with no change in layout. The CS5155 is available in 16 pin surface mount and DIP packages.
