Features  
Description  
The SC4508 is a low voltage current mode switching regu-  
lator controller that drives a P-channel power MOSFET  
with programmable switching frequency. It can be con-  
figured in either buck or buck boost (inverting) convert-  
ers. The converters can be operated from 2.7V to 15V  
input voltage range. The typical operating supply current  
is 3mA and a shutdown pin allows the user to turn the  
controller off reducing it to less than 200µA. The output  
voltage can adjusted by external resistor divider. The  
switching frequency is programmable up to 1.5MHz,  
allowing small inductor and capacitor values to minimize  
PCB space. The operating current level is programmable  
via an external sense resistor. Accessible reference volt-  
age allows users to make output voltage as low as they  
want.
