NCP1521B  
1.5 MHz, 600 mA Step-Down  
DC-DC Converter  
High−Efficiency, Low Ripple, Adjustable  
Output Voltage  
The NCP1521B step−down DC−DC converter is a monolithic  
integrated circuit optimized for portable applications powered from one  
cell Li−Ion or three cell Alkaline/NiCd/NiMH batteries. The part,  
available in adjustable output voltage versions ranging from 0.9 V to  
3.9 V, is able to deliver up to 600 mA. It uses synchronous rectification  
to increase efficiency and reduce external part count. The device also  
has a built−in 1.5 MHz (nominal) oscillator which reduces component  
size by allowing smaller inductors and capacitors. Automatic switching  
PWM/PFM mode offers improved system efficiency.  
Additional features include integrated soft−start, cycle−by−cycle  
current limiting and thermal shutdown protection. The NCP1521B is  
available in a space saving, low profile TSOP5 and UDFN6 packages.  
Features  
• Up to 96% Efficiency
