3 Board overview
The EZ-PD™ CYPAS213 + XDPS2221-based EPR 140 W USB PD charger and adapter solution
(REF_140W_HFB_PAG2S) is designed to meet the specifications as shown in Table 3.
Figure 2 shows the schematic diagram for the XDPS2221 PFC hybrid flyback in the converter stage and
the EZ-PD™ PAG2S-based single-port USB-C PD output. In this solution, the EZ-PD™ PAG2S operates at varying
frequencies depending on the control mode of the hybrid flyback (HFB) and the configurable parameter
settings.
The EZ-PD™ PAG2S IC is integrated with a synchronous rectifier (SR) and USB PD power management feature
that regulates the output voltage and current and negotiates with the connected device to provide the required
power and voltage levels.
