•
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.
