Abstract
A charger includes a thermal conductive plate for heat dissipation, and a transistor. The transistor includes a drain terminal of a first pulsating voltage level, and a source terminal of a second pulsating voltage level. The second pulsating voltage level is lower than the first pulsating voltage level. The source terminal is disposed closer to the thermal conductive plate than the drain terminal.
