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.
FIGURE 2-1:
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.
