Hi all,
I'm designing a remote control that is using nRF24L01+ as RF module (2.4GHz ISM band) and use the LM3674 as DC/DC from 3.7V 850mA/h li-on battery to 2.5V DC.
The problem is the remote control could send the data to any other module but couldn't receive any data.
Then, I realize whether if I remove the LM3674 on my remote control's PCB and supply the 2.5V with external power supply, everything works fine.
I also tried to separate the RF module's supply and leave the LM3674 on the PCB, but no luck, it doesn't work.
My questions are
1. What should I do to solve this problem ? I mean, any suggestion to measure the signal ? or which point I should check ? or I should change the DC/DC converter ?
2. if I should change the DC/DC, could you please advice ?
I'm using design ref. from webench (capacitors and resistors value)
sorry for my poor english,
Regards,
