STEVAL-ISC005V1: Stand Alone USB PD Sink Port Controller

The STEVAL-ISC005V1 evaluation board is a ready-to-use, stand alone USB PD sink based on STUSB4500. It handles the USB PD negotiation with a source to enable one or more charging paths.

An L7985 device ensures step-down conversion from the negotiated VBUS sink input to output a 5 V regulated supply which optionally allows powering an MCU evaluation board or any other system.

Several LEDs report power availability on each of the 4 available outputs. The USB PD sink port is pre-configured with three different PDOs to address a broad range of applications (5 V, 15 V and 20 V). PDOs can be easily customized thanks to a graphical user interface (GUI).
