Output Voltage Adjust (Vadj)
AllPKJ4000ESeriesDC/DCconvertershaveanOutput
Voltageadjustpin(Vadj).Thispincanbeusedtoadjustthe
outputvoltageaboveorbelowOutputvoltageinitialsetting.
Whenincreasingtheoutputvoltage,thevoltageattheoutput
pins(includinganyremotesenseoffset)mustbekeptbelow
theovervoltagetrippoint,topreventtheconverterfrom
