Adjustable Output Voltage
Step−Down Converter
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.
