Description
The STEVAL-ISC004V1 evaluation board is a ready-to-use USB PD source based on STUSB4710A and ST1S14 ICs. It demonstrates how to convert a fixed voltage DC power input into a USB PD variable voltage output. The STUSB4710A acts as a Type-C port interface that ensures power delivery advertising and negotiation, drives the DC-to-DC converter and power paths, and monitors VBUS voltage. The ST1S14 device manages the step down conversion from the DC input port to the negotiated VBUS voltage. The various LEDs indicate the operating status of the STUSB4710A and USB PD port. The USB PD port is pre-configured with five different PDOs to address a broad range of applications (5 V, 9 V, 12 V, 15 V and 20 V).
