Inverting Power Supply
« on: December 02, 2025, 03:05:12 pm »
Could someone verify the design of TPS54202 in inverting conf?

The application report includes a section describing the UVLO circuitry. Can i leave EN pin unconnected for normal operation?

Also are there better ways to make negative rail from usb-c power delivery (around 0.5A)?

application note:

You didn't read the data sheet regarding the EN pin.
It says you can leave it unconnected. RTFD.
Did you google "TPS54202 inverting configuration" It seems not.
See under for the first result that comes back!
You could have answered your own questions with few seconds of effort.
