NCP5173  
1.5 A 560 kHz−1.0 MHz  
Boost Regulator  
The NCP5173 is a switching regulator with a high efficiency, 1.5 A  
integrated switch. It runs at a base frequency of 560 kHz and can be  
synchronized to an external clock up to 1.0 MHz. This part operates  
over a wide input voltage range, from 2.7 V to 30 V. The flexibility of  
the design allows the chip to operate in most power supply  
configurations, including boost, flyback, forward, inverting, and  
SEPIC. The IC uses current mode architecture, which allows excellent  
load and line regulation, as well as a practical means for limiting  
current. Combining high frequency operation with a highly integrated  
regulator circuit results in an extremely compact power supply  
solution. The circuit design includes provisions for features such as  
frequency synchronization, shutdown, and feedback controls for  
positive voltage regulation.
