INFINEON TECHNOLOGIES EZ-PD PAG2 secondary-side controlled ZVS flyback converter chipset comprises EZ-PD PAG2P and EZ-PD PAG2S, integrates USB PD, a synchronous rectifier, and a PWM controller. Device ensures efficient communication and isolation between primary and secondary sides using pulse-edge transformer (PET) CYPET121. The chipset supports innovative noncomplementary active-clamp flyback (NCP-ACF) and quasi-resonant flyback with zero voltage switching (QR-ZVS) topologies for enhanced efficiency. This makes it suitable for high-efficiency USB-C adapters, chargers, and travel adapters. Product family delivers a versatile, efficient power delivery solution for various applications. It offers PD 3.1 standard power range (SPR) with programmable power supply (PPS) and 28V extended power range (EPR) for fast, reliable charging. Suitable for a wide range of wattages, the chipset is compatible with BC v1.2, AFC, Apple charging and QC5.0, and its universal ac line input support from 90 to 265 Vac enhances global usability.
