Keywords: SG6902 PWM controller  power adapter  green-mode 

[Summary of tips] This application note shows a step-by-step design to a 120W/24V power adapter. The equations also can be applied to different output voltages and wattages.SG6902 is designed for power supplies that consist of boost power-factor correction (PFC) and flyback pulse-width modulation (PWM). It requires few external components to ach......
