Hence, available output power is that maximum rated power is not exceeded, reduce maximum reduced by the same percentage that output voltage is output current by the same percentage increase in output voltage. trimmed down. Do not exceed maximum rated output current. 2. The trim up resistor must be connected to the +Sense pin. 2. The trim down resistor must be connected to the –Sense pin. 3. Do not trim the converter above maximum trim range (typically +10%) or the output over voltage protection circuitry may be activated. Trim resistor values calculated automatically: On-line calculators for trim resistor values are available on the vicor website at: vicorpower.com/tools.html. Resistor values can be calculated for fixed trim up, fixed trim down and for variable trim up or down cases for both 1st and 2nd Generation DC-DC converters.
