Hi I am making a RF controlled Relay for controlling my light switches in my house. I have the RF side of my board down but I'm having trouble with the power supply. I purchased the BP5034D5 power module from Rhom. Here is the datasheet link https://www.rohm.com/products/databook/pm/pdf/bp5034d5.pdf. I have the power module connected as shown in the application circuit and I'm getting a 5volt output. I am having trouble however with my decoder circuit (433 Mhz) when its powered by the AC power module. For some reason when I have the power module powering the circuit my RF decoder behaves differently than when I connect it to a steady 5VDC power source. I believe that EMI could be causing issues but it seems strange since the problem is not erratic. Normally when I push a button on the transmitter side I have it set up so that the pin is latched on the decoder side. But when I have the AC power module powering the circuit the decoder acts like its in momentary mode, the pin only stays low as long as I hold the button down on the transmitter, once released it goes high.
Do you think this is a problem with Electromagnetic Interference and if so what can I do to shield or fix this.
Thanks you very much for all help! This problem has been killing me lately as I am not very familiar with EMF or AC power.
