NCP1529  
1.7MHz, 1A, High Efficiency,  
Low Ripple, Adjustable  
Output Voltage Step-down  
Converter  
The NCP1529 step−down DC−DC converter is a monolithic  
integrated circuit for portable applications powered from one cell  
Li−ion or three cell Alkaline/NiCd/NiMH batteries. The device is able  
to deliver up to 1.0 A on an output voltage range externally adjustable  
from 0.9 V to 3.9 V or fixed at 1.2 V or 1.35 V. It uses synchronous  
rectification to increase efficiency and reduce external part count. The  
device also has a built−in 1.7 MHz (nominal) oscillator which reduces  
component size by allowing a small inductor 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 NCP1529 is available in a space saving, low profile  
2x2x0.5 mm UDFN6 package and TSOP−5 package.  
Features  
• Up to 96% Efficiency  
• Best In Class Ripple, including PFM mode  
• Source up 1.0 A
