CS5150H

CS5150H CS5150H CPU 4-Bit Synchronous Buck Controller Description The CS5150H 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 CS5150H is designed to operate over a 4.25-20V range (VCC) using 12V to power the IC and 5V or 12V as the main supply for conversion. The CS5150H is specifically designed to power Pentium® Pro processors and other high performance core logic. It includes the following features: on board, 4-bit DAC, short circuit protection, 1.0% output tolerance, VCC monitor, and programmable soft start capability. The CS5150H is upward compatible with the 5-bit CS5155H, allowing the mother board designer the capability of using either the CS5150H or the CS5155H with no change in layout. The CS5150H is available in 16 pin surface mount.
