Test Procedure for the NCP1256B60WGEVB Evaluation Board

Overview

TopologyFlyback Converter
Input voltage85-265 V
Output 119 V / 3.3 A

Description

An ac source, delivering 80 V ac to 265 V ac, needed power is below 100 W. An electronic source or a simple variac can do.2. An input ac watt-meter, up to 100 W3. A dc load absorbing up to 100 W, Vin,max < 30 V, Iout,max < 5 A4. Either the above load can display dc V and dc A or separated V and A-meters are necessary If the load does not use local Kelvin sensors, then the output voltage must be measured at the board level, not at the cable ends.
