DESCRIPTION
The UTC UC3383 Series are PFM step-up DC/DC switching
converter. The UTC UC3383 can support both large and small
currents. It automatically switches duty ratio (45%/75%) when it
senses changes in load.
Both built-in and external transistor types include 5-pin and 3-pin
packages, which are provided with either a CE (chip enable)
function that reduces power consumption during shut-down mode,
or a VDD pin function (separated power and voltage detect pins).

Note: 1. The Schottky diode (SD) must be type MA735, with reverse current(IR)<1.0μA at reverse voltage (VR) =10V.
2. "Supply Current 1" is the supply current while the oscillator is continuously oscillating. The current actually
provided by an external VIN source is represented by "No-Load Input Current (IIN)".
