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.
