Product overview

Description

The STEVAL-2STPD01 is an 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.

Once the input power rate is fixed, the kit is able to balance the power on the two ports, supporting the requests sent by the USB PD devices connected to each port.

Taking advantage of STPD01PUR characteristics to output several voltage levels, the solution is able to manage up to 120 W (60 W for each port) according to the DC input power.

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.

To fully demonstrate the USB Type-C and Power Delivery functionalities of the solution, the STSW-2STP01 software package, containing the demo application example, has been designed for the NUCLEO-G071RB STM32 Nucleo development board.

The solution is compliant with USB Type-C 2.1 and PD 3.1 specifications.
