The CS5161/5161H are 5–bit synchronous dual N–Channel buck
controllers designed to provide unprecedented transient response for
today’s demanding high–density, high–speed logic. They operate
using a proprietary control method which allows a 100 ns response
time to load transients. The CS5161 is designed to operate over a

9–16 V range (V ) using 12 V to power the IC and 5.0 V as the main
CC
supply for conversion.
The CS5161H operates from a 12 V input as the main supply for
conversion using a discrete charge pump circuit to provide up to 20 V
