I want to get 1.0V output on ch2 of the adp5052. And the FB2 of adp5052 is 0.284V.
Any and all help is appreciated.
How about other voltage channels? Please check if feedback resistor good solder on the board?
And if EN2 voltage is about 5V? Thanks.
Hi Jason, EN2 is 5V and the feedback resistor is ok.But the out put of DL2 is
Hi, I found that while the resistor is 31.6kΩ， the frequency of sw2 is 1kHz. and while the resistor is 10kΩ， the sw2 is 297kHz. Why?
If the switching frequency of the other channel is correct according to RT, then problem could be related to connection or PCB layout. Please make sure that the recommended PCB layout in datasheet is followed. It maybe helpful that you look at waveforms of SW2, VIN, VOUT during start-up to see the behavior..
