1 Application overview
PAGxP works with secondary-side controller PAGxS. Figure 1 shows the application diagram of a USB Power Delivery (USB PD) Power Adapter solution with ‘PAG2P +PAG2S’ . In this system, once the start-up phase is complete, the primary FET control is completely synchronized to the PWM pulses received from the secondary-side. The PWM pulses are transmitted over an isolation barrier using this PET .
