Notes:

1. The UCD9240PCF (U8) synchronizes the PTD power stages (U10 and U41) so that a maximum of 40A can be supplied to the

VCCINT rail

Using External Power Sources

The maximum output current rating for each power regulator is listed in

design exceeds this value on any power rail, power for that rail must be supplied through

the external power jack using a supply capable of providing the required current.

Each power rail has a corresponding jack and jumper that is used to supply voltage to the

rail using an external power supply. The jack, jumper, and regulator for each power rail is

listed in

1-1. The board can also be configured to use external bench power supply for each
