I have an Autek IFIX919 diagnostic kit that an ic has failed on the 5v input line from the usb port. The ic is labelled up as A17O2 or A1702
The pin designation from this are as follows:
Pins
1 = Not sure
2 = GND
3 = 3.3V output line
4 = 5V input from the usb port
5 = suspect a feedback line
I have looked up for the smd code but cannot find anything suitable.
It could be LDO voltage regulator 3.3V
Basically the gnd and 5V has a short across it of around 26ohms.
The ic is marked up as U4 which has been highlighted in a red box.
I have been looking at the output and the pcb I have traced goes to an 3.3V line.
Any help would be appreciated in identifying would be great.
