A8483 Step-up Converter

Pin Functions VIN. Supply to the control circuit. A bypass capacitor, C1, must be connected from close to this pin to GND. GND. Ground reference connected directly to the ground plane. The feedback resistor should have a separate connection directly to this point. EN. Voltage lower than 0.4 V disabl.
