APPLICATION NOTES
RoHS COMPLIANCE INFORMATION
OUTPUT VOLTAGE ADJUSTMENT
INPUT REFLECTED RIPPLE CURRENT
When the output voltage is trimmed up, output current must be derated so that the maximum output power (shown in the selection table) is not exceeded.
Input refl ected ripple current is measured with the following components connected to the power supply and across the input of the NPX20 DC/DC converter.
A 33μF low ESR (<0.7Ω) capacitor is connected across the input of the NPX. A large bulk capacitor 220μF (<100mΩ) is connected across the power supply,
followed by a series fi lter inductor of 12μH measured using current probe, scale 1mV/mA.
