3.6 Power Supply Connection

Connect the power supplies and load to the TPS2410 test card as shown in Table 3. Loading less than 30

A is safe for IRl3713S. The load can be a test load or the actual system load.

3.7 OV and UV Setup

Set the OV and UV pots for each input voltage selected and re-adjust these pots when the input voltage

range is changed.

For this example, PS1 and PS2 are 12 V ±20 %. Set PS1 to the under-voltage set point, 9.6 V, and adjust

R13 until TP7 measures 0.6 V, reference Table 4. Set PS1 to the over-voltage set point, 14.4 V, and

adjust R12 until TP10 measures 0.6 V.

Complete this procedure for channel 2. Set the power supply voltages, PS1 and PS2, to the typical input,

12 V.
