The EVLSTCH03-45WPD is an isolated power supply with a standalone USB PD controller. The evaluation board implements at the primary side a quasi-resonant flyback converter based on the STCH03 controller with optocoupler feedback for voltage regulation. This controller combines a high performance low-voltage PWM controller chip with a 650 V HV start-up cell in the same package. The STCH03 controller drives the gate of the new 650 V MDmesh M6 technology Power MOSFET STD7N65M6. At the secondary side, to increase the system efficiency, the rectification is based on the SRK1001 adaptive synchronous rectification controller. This controller drives the gate of the 100V STripFET F7 technology Power MOSFET STL110N10F7. Always on the secondary side the CC/CV regulation loop to drive the power regulation stage and the USB Type-C PD interface are based on the STUSB4761 controller. This controller offers the benefits of a full hardware USB PD stack allowing robust, deterministic and safe negotiation in line with USB PD standard. The EVLSTCH03-45WPD is protected against destructive electrostatic discharge from the USB Type-C connector using a Dual Transil array for ESD protection ESDA25L.
