NCP1501  
Dual Mode PWM/Linear  
Buck Converter  
The NCP1501 is a dual mode regulator that operates either as a  
PWM Buck Converter or as a Low Drop Out Linear Regulator. If a  
synchronization signal is present, the NCP1501 operates as a current  
mode PWM converter with synchronous rectification. The  
synchronization signal allows the user to control the location of the  
spurious frequency noise generated by a PWM converter. Linear mode  
is active when a synchronization signal is not present. The NCP1501  
configuration allows an efficient high power operation and low noise  
during system sleep modes.
