Test Setup:

DUT: PI2007-EVAL1

Vin1 = 48V

Vin2 = 48V

Output Load = 6A

Test:

Both input sources are

turned on and sharing the

load current, then applied a

short for 1ms with a fast turn

on MOSFET between Vin1

and Rtn.

Test purpose:

To show the PI2007 response

to a fault condition, where

the output of the input

source is shorted or tried to

source current from the load
