150W Single Output
Output Voltage Adjustment
The output voltage is adjustable from 0% to +20% trim up of nominal output voltage by connecting an external resistor between
the TRIM1 and TRIM2 pins. With an external resistor between the TRIM1 and TRIM2 pins, the output voltage set point
increases. The maximum output deviation is +20%. The value of external resistor can be obtained by trim table shown in next
page.
