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
(Vout)
