Wating for your response..Sincerely yours, Jake Kang.Edited) It is because the datasheet said that VINV is for INVERTER INPUT. If anyone have an idea, please keep me in the loop.

Dear willzhou, sorry for the late reply. Yes, the recording was done by following the datasheet. When load attatched on the RX's side, TX Power is higher than RX Power.↓But, when no load on the RX's side, TX Power is lower than RX Power. So, the grap...

Hello, I just finished setting FOD parameter from the TX's sideBut I omitted setting the RX side's FOD parameter.I tested several FO's that i set out to detect and send EPT's.It worked fine, the power transmitting terminated when FO-detected.In this ...

I started increase the load, from 100mA to 1,000mA in 100mA step. The Vout remains stable.For our product, power could be 1.35 ~ 2.5W or so (300~500mA , by setting Vout 4.5 V - to 5.0 V).I have to test further, but it seems the problem solved.Thank Y...

It was not the fluctuation nor the STWBC's problemIt was setting high voltage regarding the Mux's input.When setting Vout 5V → 4.5V , problem disappeared.
