Description

The CS5151 is a 4-bit nonsynchronous 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 CS5151 is designed to operate over a 4.25-16V range (VCC) using 12V to power the IC and 5V as the main supply for conversion.
