4 EVALUATION BOARD OPERATING PROCEDURE
CAUTION: Potentially lethal voltages exist on this demo board when powered up. Improper
or unsafe handling of this board may result in serious injury or death.
4.1 Load Connection
Connect a resistive or electronic load, capable of 150W continuous power on the 24V rail to connector JP4 and
a 75W continuous power load on the 12V output rail to JP5. Please note that there is no minimum load
3
requirement for this board.
3
A minimum load has been added on both the output rails to ensure tight voltage regulation for both output rails from no
load to full load.
