NCP1500  
Dual Mode PWM/Linear  
BUCK Converter  
The NCP1500 is a dual mode converter that operates as either a  
pulse width modulated (PWM) buck converter or as a linear regulator.  
The converter automatically transitions between the two modes. The  
converter operates as a PWM when a synchronization signal is present  
at the sync input. The converter operates as a linear regulator in the  
absence of a synchronization signal. The PWM mode offers excellent  
performance at normal to heavy loads at the sacrifice of output ripple  
voltage. The linear mode offers excellent noise rejection at the  
sacrifice of system efficiency. The user is able to select which mode  
will give the best performance for a given operating condition.  
Internal protection features include thermal shutdown with hysteresis  
and cycle−by−cycle current limit in the PWM mode. Additionally, the  
converter transitions into PFM mode at very light loads if a  
synchronization signal is present and an output overvoltage condition  
is detected.
