An Adaptive Variable-Frequency Control With Constant Crossover Frequency Achieving Fast Transient Response for Wide-Operation-Range Flyback Converter

Flyback converters with universal serial bus power delivery (USB-PD) specification are widely used in low-power adapter application. The wide output voltage range operation of USB-PD makes the loop gain vary under different working conditions. To ensure stability in all working conditions, the loop...
