Table 3 • Test Point Connections
Name
Description
VIN
Device power input connector.
VOUT
Device power output connector.
GND
Ground pin for both input and output.
The following steps describe the test procedure.
Before connecting the power supply to the VIN and GND connector pins, set the power supply
voltage to 12 V.
Turn on the power supply. Use the oscilloscope to measure the soft start output voltage. The soft
start time should be 1.2 ms.
Start to increase the load current up to trigger thermal shutdown. Check the over-current level and
EN pin voltage. EN voltage should be around 1.7 V. Over current limit is around 3.5 A.
