NCP3170  
Synchronous PWM  
Switching Converter  
The NCP3170 is a flexible synchronous PWM Switching Buck  
Regulator. The NCP3170 operates from 4.5 V to 18 V, sourcing up to  
3 A and is capable of producing output voltages as low as 0.8 V. The  
NCP3170 also incorporates current mode control. To reduce the  
number of external components, a number of features are internally set  
including soft start, power good detection, and switching frequency.  
The NCP3170 is currently available in an SOIC8 package.
