NCP1521B  
1.5 MHz, 600 mA  
Step−Down DC−DC  
Converter  
High−Efficiency, Low Ripple, Adjustable  
Output Voltage  
http://onsemi.com  
The NCP1521B step−down PWM DC−DC converter is optimized  
for portable applications powered from one cell Li−ion or three cell  
Alkaline/NiCd/NiMH batteries. The part is available in adjustable  
output voltage versions ranging from 0.9 V to 3.3 V. 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 space saving, low profile TSOP5 and UDFN6 packages.  
Features  
• Up to 96% Efficiency
