The CS5151 is a 4-bit nonsyn-

chronous N-Channel buck con-

troller. It is designed to provide

unprecedented transient response

for today’s demanding high-densi-

ty, 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.

The CS5151 is specifically designed

to power Pentium® processors with

MMX™ Technology and other high

performance core logic. It includes

the following features: on board,

4-bit DAC, short circuit protection,

1.0% output tolerance, VCC monitor,

and programmable soft start capa-

bility. The CS5151 is upwards com-

patible with the 5-bit CS5156, allow-

ing the mother board designer the

capability of using either the

CS5151 or the CS5156 with no

change in layout. The CS5151 is

available in 16 pin surface mount

and DIP packages.
