Original CM6901 CM6901X CM6901XISTR SOP-16 ynchronous rectifier chip

CM6901XISTR is an SLS, SRC/LLC + SR resonant controller on APW3++ power supply, and it can work in SRC and LLC area, synchronous rectification for high efficiency. In addition, it is used for DC-DC conversion in offline applications. Its light load regulation is achieved by switching the controller from frequency modulation mode to PWM mode. To achieve the best balance performance between hold-up time and efficiency, its frequency range spans fr1 (resonant frequency).
