CS5155GDR16

Description
The CS5155 is a 5-bit synchronous dual N-Channel buck controller. It is designed to provide unprece dented 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 (VCC) 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, VCC monitor, and programmable soft start capability.
The CS5155 is backwards compatible with the 4 bit CS-5150, allowing the mother board designer the capabili ty 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.
