Controllers | CS5151H

The CS5151H is a 4-bit nonsynchronous 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 CS5151H is designed to operate over a 4.25-20V range (V_CC) using 12V to power the IC and 5V or 12V as the main supply for conversion.

The CS5151H is specifically designed to power Pentium ^â processors with MMX™ Technology and other high performance core logic. It includes the following fea-tures: on board, 4-bit DAC, short circuit protection, 1.0% output tol-erance, VCC monitor, and programmable soft start capability. The CS5151H is upwards compatible with the 5-bit 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.
