Step−Down Converter

http://onsemi.com

The NCP1522 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 3.0 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 NCP1522 is

available in a space saving, low profile TSOP5 package.
