1. The white LED can be used in seies, regardless of the number of connection of the LED, a resistor can provide them with a constant current; 2. A LED resistor can adjust the operating current of white LED; 3. Ceramic capacitors can be used to obtain low ripple noise, and extend the life of the circuit; 4.It can greatly reduce circuit space: XC9105 and FET + SD are available in SOT23 packages, nad the maximum coil thickness is only 1.2 mm, the input and output capacitors are ceramic capacitors.
