STEVAL-2STPD01

Evaluation kit composed of an expansion board containing two Type-C ports and integrating two STPD01PUR programmable buck converters for USB power delivery and the NUCLEO-G071RB STM32 Nucleo-64 development board. The kit exploits the characteristics of the STPD01PUR programmable buck regulator controlled through I²C interface and the UCPD peripheral embedded in the STM32G071RBT6 microcontroller supported by a dedicated firmware stack to implement a USB Type-C and PD dual port source adapter with power sharing capability. The expansion board has been specifically developed to be stacked on the NUCLEO-G071RB development board using the capability of its microcontroller to manage two UCPD peripherals at the same time. It also embeds the TCPP02-M18 USB Type-C port protection for source applications and the L7983PU50R synchronous step-down switching regulator.

• Two USB Type-C and power delivery source ports
• Output power up to 120W-rated (60W per port), managed through power sharing algorithm
• Up to four output PDOs for each port (5Vat 3A, 9V at 3A, 15V at 3A, 20V at 3A)
• Compliant with USB Type-C 2.1 and PD 3.1 specifications
• 2 DC-DC converter dynamically set by I²C, suitable to implement power sharing in USB PD applications
• Two on-board TCPP02-M18 protections for USB Type-C and PD Source applications
• OVP, UVP, OC, short-circuit and OTP protections
• Surge protection (8/20 µs) and system level ESD protection on VBUS
• System level ESD protection on CC lines as per IEC61000-4-2 level 4 (±8 kV contact discharge)
