CPU 5−Bit Synchronous Buck Controller

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.
