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.
FEATURES
* 0.8V Start-Up Voltage
* Low Supply Current of Typical be18μA
* Wide Output Voltage Range of 2.5V~5.0V
* Output Voltage Accuracy ±5%
* Output Current Up to 100mA
* Low Ripple and Low Noise
* High Efficiency Up to 85%
* Low Profile and Minimum External Components
