Hello Team,

We have designed our circuit according to adp5054 ref (ADRV9371-W_PCBZ_Schematic_RevA),the setting as follows:

input:12v

output:

      mode: FPWM

      freq:600khz

      ch1:1.3v

      ch2:1.3v

      ch3:3.3v

      ch4:1.8v

 

 

But we are observing output as follows

ch1:10v not 1.2v!!!!

ch2 is okay,

ch3:0.8v not 3.3v!!!

ch4 is okay,

Please let us know if we are missing out something.

Please find the Attached Pdf of our design schematics.

 

Thanks,

Ashok.
