Getting started with the STEVAL-ISC004V1 evaluation board for the
STUSB4710A USB PD controller with on-board DC-DC
Introduction
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 V
voltage.
BUS
The ST1S14 device manages the step down conversion from the DC input port to the negotiated V
voltage.
BUS
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).
