Chapter 2. Board Details & Configuration

The Microchip EVB-USB5734 is designed for flexible configuration solutions. It can be

configured via default internal register settings, downloadable external firmware to an

on-board SPI Flash, through SMBus, or through the on-board configuration switches.

When configured with the default internal register settings, the device operates as a

USB 3.0/2.0 hub with four battery charge enabled USB ports and Microchip’s standard

VID/PID/DID settings.

This chapter describes details on the EVB-USB5734 Power, Clock and Configuration.

INITIAL CONFIGURATION

2.1

POWER SOURCE - SELF-POWERED

The EVB-USB5734 only supports self-powered operation, and is powered through one

+12.0V regulated external power supply. The power supply plugs into the 2.5mm con-

nector J9 on the board. Alternatively, an external voltage can be injected onto the J6

Ext. 12V header, which is not populated by default. The +12.0V feeds a 6A regulator

which outputs +5.25V across the board. This +5.25V output supplies the +3.3V and

+1.2V on-board regulators and VBUS for the DFPs.
