7. Enable the power supply and verify the current limit magnitude and auto-retry fault response waveform as
shown in
.
Figure 4-3. J5/J12 = 2-3 Position, Current Limit (2.23 A), Auto-Retry Mode
8. Disable the power supply.
9. Set the current limit response mode to latch-off by installing the J4/J11 jumper in the position 1-2.
10.Set the load resistance to 6 Ω ±1 Ω and enable the load.
11.Enable the power supply and verify the current limit magnitude the latch-off fault response waveform as
shown in the
.
Figure 4-4. J5/J12 = 1-2 Position, Current Limit (2.23 A), Latch-Off Mode
12.Once the device is latched-off, either the power supply or the SHDNb should be recycled to re-enable it.
13.Change the load resistance to 16 Ω ±1 Ω.
