ACDC充电器详解AN2228 APPLICATION NOTE STD1LNK60Z-based Cell Phone Battery Charger Design Introduction This application note is a Ringing Choke Converter (RCC)-based, step-by-step cell phone battery charger design procedure. The RCC is essential to the self-oscillating fly-back converter, and operates within the Discontinuous Conduction Mode (DCM) and Continuous Conduction Mode (CCM) boundaries without noticeable reverse recovery of the output rectifying diodes. RCC control is achieved by using discrete components to control the peak current mode, so the overall RCC cost is relatively low compared to the conventional Pulse Width Modulation (PWM) IC fly-back converter. As a result, RCC is widely used for low power applications in industry and home appliances as a simple and cost-effective solution. Figure……
