Hi davidtosenovjan，

I saw all the power domain are connected to VDD_HV directly, such as VDD_HV_FLA, VDD_HV_A / B /C. Does it mean that we have to use 3.3V supply for this board only?

Because on Data sheet, it mentioned:

3. VDD_HV_FLA must be connected to VDD_HV_A when VDD_HV_A = 3.3V
4. VDD_HV_FLA must be disconnected from ANY power sources when VDD_HV_A = 5V.

BTW, my customer used all power domain @ 5V., and connect one 2.2uF decoupling capacitor to VDD_HV_FLA only.

Yes, it seems so. I will check whether some user guide exist.
