I used a TI reference designto prototype a 120VAC to 5VDC 2A power supply on a PCB and it's been working fine for a couple of months. I want to run some basic tests to see if the PCB is safe under over voltage and over current scenarios. Is there a cheap way to go about doing that? I came across Hipot testers, but they were pretty expensive.

  • \$\begingroup\$ Are you trying to test its integrity? If so, why? TI already has information on this. \$\endgroup\$ – KingDuken May 1 '18 at 20:32

Only thing not given is HIPOT which depends on creepage clearance and T1

HIPOT 4kVdc testers are simple to make with line multiplier and 1000k 1W current limiter with variac or Triac dimmer for a few second ramp to charge up line filter caps. 1mA analog current meter is needed with protection diodes
