User Guide
General Description
The 65W 2C+1A PD 3.0 PPS Adaptor EVB is designed to support two main objectives. First, meet Energy Regulation for efficiency and standby power with acceptable thermal performance and Second, support smart dynamic power sharing scheme among three charging Ports-2 Type C PD ports and 1 Type A port. The design is a two-stage flyback+DC/DC Buck power topology to support three independent charging ports – arranged as Stage 1, AC to-CV (Constant Voltage) input stage and Stage 2, CV- to-Charging DC output stage. The system configuration is organized as two main paths – dual Type C PD Paths for charging two PD capable devices and one Type A Path for charging Type A device. The AC-to-CV power stage is composed of three main PREMA parts -1) Primary side CCM/QR Flyback controller–PP5200, offers the CM/CCM PWM switching, 2) 650V/200mohm GaN Transistor–PP6262 and 3)Secondary side SR controller–PP6008, supports Synchronous Rectification under DCM or CCM operation mode.
