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.
