The CS5157 is a 5-bit synchronous dual N-Channel buck controller 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 CS5157 is available in 16 pin surface mount.
The CS5157 is a dual N-Channel buck controller specifically designed to provide unprecedented transient response for today's demanding high-density, high-speed logic. It operates using a proprietary control method that allows a 100ns response time to load transients and includes features such as an on-board 5-bit DAC, short circuit protection, Vcc monitor, and programmable soft start capability.
