CPU 5-Bit Nonsynchronous Buck Controller
The CS5156H is a 5–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 100 ns response time to load transients. The CS5156H is designed to operate over a 4.25–20 V range (VCC) using 12 V to power the IC and 5.0 V or 12 V as the main supply for conversion.
