## **CYPET121, CYPET131** A/™ **EZ-PD™ PAGxP-PAGxS pulse edge transformer (PET)**
## **General description**
Pulse Edge Transformer (PET) is used as a medium to transmit PWM pulses from secondary-side i.e., PAGxS controller to primary-side i.e., PAGxP for AC/DC applications targeting the power adapter segment.

**EZ-PD™ PAGxP-PAGxS pulse edge transformer (PET)**
Application overview
## **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.
