A power tip that discusses how to address highly integrated USB PD charger design constraints with a self-biasing circuit.

However, a small magnetizing inductance is inevitably used due to low zero-voltage-switching (ZVS) current, and some diodes still suffer from high voltage stress. In addition, during the freewheeling ...

but the voltage gain of the LLC converter can be increased significantly with a narrow switching frequency range and a smaller magnetizing inductance circulating current. In addition, the proposed ...
