Make sure Enable switch is set to OFF position
By default, the module is configured to set Vout with pin-strap resistors.
Make sure jumper in the position 10 is populated with desired Vout.
Connect power supply to connectors on position 1.
Connect load to connectors on position 2.
Connect the PMBus adapter/cable to the board.
Apply Vin = 6-15V through connectors on position 1.
Set Enable switch to ON position. The power good LED will give green
light.
Note: PG LED is powered by USB-PMBus adapter, so only connect demo
board with computer through adapter, LED will be lit when module Vout is
ready.
Then increase the load, and through K2 (position 7) to measure the Vout
and ripple.
Set Enable switch to OFF position
Turn off Vin
