STEP-UP DC/DC CONVERTER



DESCRIPTION

The UTC UC8383 is a high efficiency VFM controlled step-up

DC/DC converter. The UTC UC8383 is designed to have low start

up voltage and low quiescent current: The UTC UC8383 can

realize the conversion from the input voltage to the selected

output voltage (2.5V ~ 5.0V) only using an inductor, a diode and

an output capacitor.

Its typical applications include: cellular telephones, pagers,

video camera, PDA and hand held instruments, palmtop,

notebook computer, portable equipment and battery powered

equipment.


