ON Semiconductor CS5159 CPU 5-Bit Synchronous Buck Controller Datasheet

The CS5159 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 100 ns response time to load transients. The CS5159 is designed to operate over a 4.25-16 V range (VCC) using 12 V to power the IC and 5.0 V or 12V as the main supply for conversion. The CS5159 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 CS5159 is available in 16 pin surface mount.
