CS51031  
Fast PFET Buck Controller  
Does Not Require Compensation  
Features  
Description  
The CS51031 is a switching con-  
troller for use in DC-DC converters. allows the use of small inductors  
The high frequency oscillator  
1A Totem Pole Output  
Driver  
It can be used in the buck topology  
with a minimum number of exter-  
nal components. The CS51031 con-  
sists of a VCC monitor for control-  
ling the state of the device, 1.0A  
power driver for controlling the  
gate of a discrete P-channel transis-  
and output capacitors, minimizing  
PC board area and systems cost.  
The programmable soft start  
reduces current surges at start up.  
The short circuit protection timer  
significantly reduces the duty cycle  
to approximately 1/30 of its cycle  
High Speed Oscillator  
(700kHz max)  
No Stability

VCC Monitor  
The CS51031 is available in 8L SO  
grammable soft start, precision ref-  
and 8L PDIP plastic packages.
