ADM00902 DEMONSTRATION BOARD FOR EMC2103 DESCRIPTION

The ADM00902 Demonstration Board for EMC2103 becomes fully functional when it is 
powered through the USB connector and the 12V BOOST for the V

FAN

 supply is 

selected. The total power consumption of the board is slightly below the 2.5W that the 
USB port can supply. The external 12V jack (J2) or test points (TP1 and TP2) are 
needed when using another fan with a higher power consumption.
The maximum voltage supported by the jack and the power test point connections is 
16V, limited by the 3.3V regulator that is powering the low-voltage circuits.
The communication with the PC is provided through the MCP2221A device, a USB to 
I

2

C/SMBus bridge.

There is one fan channel available which uses a Switch mode PWM driver for higher 
efficiency and three remote diode channels accessible through the J11 connector.
The on-board EEPROM (U4) holds the device configuration and can be used to load 
the settings at power-up by setting the appropriate SHDN_SEL jumper (J6).
