3.1.2 Powering-up the DLPC4420AEVM and Preparing for the DLPC4420AEVM to be Programmed

Before powering up the EVM, make sure the included DLPC4420AEVM jumpers are in the correct positions. The jumper locations are listed in Table 4-1.

Table 3-1 Reference Designators
JumperDescription (Bold Indicates Default Position)

Pins 2,3 connected Comparator Sensor
J40 - High current Fan 5 or Fan 6Pins 1,2 connected for high current fan 5
Pins 2, 3 connected for fan 6

Jumper J31 is the Hold BL jumper. This jumper is used to put the DLPC4420AEVM into boot loader mode, which allows the DLPC4420 controllers to be programmed. Connect this jumper to prepare the DLPC4420AEVM to be programmed.

To power up the DLPC4420AEVM, a 12 V, 5 A power supply is needed. Make sure the power supply is functional and the switch SW1 on the EVM is set to off before connecting the power supply to the EVM. Connecting the power supply when the switch is in the off position can prevent damage to the DLPC4420AEVM from poor power connections. The image below shows SW1 in the on position.

Once the power supply has been connected to the DLPC4420AEVM, the switch SW1 can be flipped to the on position. You can then plug in the USB cable into the board to prepare for programming the board.
