Quiescent Current,  
Adjustable Output Voltage  
Step−Down Converter  
http://onsemi.com  
The NCP1521 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 device is available in an adjustable  
output voltage 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 a small inductor and capacitors. Automatic switching  
PWM/PFM mode offers improved system efficiency.

Finally, it includes an integrated soft−start, cycle−by−cycle current  
limiting, and thermal shutdown protection. The NCP1521 is  
available in space saving, low profile TSOP5 and UDFN6 packages.
