CS5151H

The CS5151H is a 4bit nonsynchronous NChannel buck controller. It is designed to provide unprecedented transient response for today's demanding highdensity, highspeed 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 4.2520 V range (V_CC) 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 MMXE^TM Technology and other high performance core logic. It includes the following features: on board, 4bit DAC, short circuit protection, 1.0% output tolerance, V_CC monitor, and programmable Soft Start capability. The CS5151H is upwards compatible with the 5bit CS5156H, allowing the mother board designer the capability of using either the CS5151H or the CS5156H with no change in layout. The CS5151H is available in 16 pin surface mount package.
