CS5150  
CPU 4-Bit Synchronous Buck Controller  
Features  
Description  
The CS5150 is a 4-bit synchronous  
and other high performance core  
logic. It includes the following fea-  
tures: on board, 4-bit DAC, short  
circuit protection, 1.0% output tol-  
erance, VCC monitor, and pro-  
Dual N-Channel Design  
Excess of 1MHz Operation  
100ns Transient Response  
4-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  
grammable soft start capability. The  
Upward Compatible with  
5-Bit CS5155/5156 and  
operates using a proprietary control CS5150 is upward compatible with  
method, which allows a 100ns  
response time to load transients.  
The CS5150 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 5-bit CS5155, allowing the  
Adjustable CS5120/5121  
mother board designer the capabili-  
ty of using either the CS5150 or the  
CS5155 with no change in layout.  
The CS5150 is available in 16 pin  
surface mount and DIP packages.
