STMicroelectronics EVLSTCH03-45WPD USB Type-C™ Power Delivery Adapter
STMicroelectronics EVLSTCH03-45WPD 45W USB Type-C™ Power Delivery Adapter is a USBIF-certified solution and reference design. STMicroelectronics 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 650V HV start-up cell in the same package. The STCH03 controller drives the gate of the STD7N65M6 650V MDmesh™ M6 technology Power MOSFET.
On 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 is used to drive the power regulation stage and the USB Type-C PD interface, which 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 standards.
The EVLSTCH03-45WPD is protected against destructive electrostatic discharge from the USB Type-C connector using a Dual Transil array for ESD protection ESDA25L. The evaluation board implements a robust adapter protected for output overvoltage, output under-voltage, output overpower, and output short-circuit. This reference design helps designers to develop adapters with a short bill of materials to obtain a cost-effective and fast design.
