Part Number: TRF3765EVM

I bought TRF3765EVM REV E.

I think +5.0V Connection to Regulators is not connected. I tested the connection is open.

Is there any other problem if I connect 5V of USB output to + 5.0v?

Hi BH,

To use these regulated 3.3-V supplies, disconnect power from TP2 and remove R41. Connect 5 V to TP26, using TP27 for ground. Place jumpers on JP4 and JP5 to shunt jumper pins 1 and 2.

If you use the 5V from a USB device, make sure it is capable of supplying 250 mA.

Thank you, Fung.

I should have read the datasheet 2.2.

Default Power Supply mode is the EVM board uses external power supply connected 3.3V TP.

Regards, Fung
