CS5158  
CPU 5-Bit Synchronous Buck Controller  
Features  
Description  
The CS5158 is a 5-Bit synchronous  
The CS5158 is specifically designed  
to power Pentium® II processors  
and other high performance core  
logic. It includes the following fea-  
tures: on board, 5-Bit DAC, short  
circuit protection, 0.8% output tol-  
Dual N-Channel Design  
Excess of 1MHz Operation  
100ns Transient Response  
5-Bit DAC  
dual N-Channel buck controller. It  
is designed to provide unprece-  
dented transient response for  
today’s demanding high-density,  
high-speed logic. The regulator  
Backward Compatible with  
operates using a proprietary control erance for the 01111 DAC code  
Adjustable CS5157  
method, which allows a 100ns  
response time to load transients.  
The CS5158 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.  
(1.3V) and 1% for the remaining  
DAC codes, VCC monitor, and pro-  
grammable soft start capability. The  
CS5158 is available in 16 pin surface  
mount.
