Controllers | CS5155H
概览
The CS5155H is a 5-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 CS5155H 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 CS5155H is specifically designed to power Pentium â II pro-cessors 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 CS5155H is backwards compatible with the 4 bit CS5150, allowing the mother board designer the capability of using either the CS5150 or the CS5155H with no change in layout. The CS5155H is available in 16 pin surface mount.
