Getting started with the STEVAL-2STPD01 USB Type-C™ Power Delivery dual
port adapter based on the STPD01 programmable buck converter
Introduction
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
development board.
The kit exploits the characteristics of the
UCPD peripheral embedded in the
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
(60 W for each port) according to the DC input power.
The expansion board has been specifically developed to be stacked on the
capability of its microcontroller to manage two UCPD peripherals at the same time. It also embeds the
Type-C port protection for Source applications and the
To fully demonstrate the USB Type-C and Power Delivery functionalities of the solution, the
