Test Procedure for the NCP1605 Forward Evaluation Board

Apply a resistive or an active load across the output (between the “+V

load must be able to draw 12 A from 19 V (use a 25 V or more voltage load for a safe headroom).

To evaluate the board performance, it is recommended to place a power analyzer able to measure:

As portrayed by figure 1, this power-meter should be inserted between the power source and the board (the power

source being defined in next point).

Plug the application to a 250 W or more, isolated ac power source. This source that is applied, is supposed to simulate

the line utility. Hence, the power source voltage should be a 50 or 60 Hz sinusoid (without dc component). Its

magnitude must remain below 265 Vrms.

You can them measure the board performance presented in ANDxxxx. Among them, we can list:

•

The power delivered by the power source (“Pin”),

The power factor (“PF”) and the Total Harmonic Distortion (“THD”) of the current absorbed from the ac

power source.

Apply 120 Vrms and load the output with 8 A

Decrease the load current. When I

can check it by observing the line current that must be bursting.

Increase the load current until 19 V output voltage drops. The load current should be less than 12 A and the

power supply should be hiccupping. Again, you can check this by observing the line current. This test must

be very short to avoid any excessive heating of the board (designed for I

if the power supply does not enter hiccup mode while I

iii. The input power should be less than 190 W

ii. The power factor should be higher than 0.990

i. The output voltage should be between 18.5 and 19.5 V.
