        Thank you! Yes, this is the one.

        About the second one, have some updates

        It is from a BRC1HHDAK - Daikin Madoka wired remote control.
        I was try to get some schematic from PCB - hope it help...

        It looks to be some buck converter (step-down) - fixed voltage
        Any info is wellcome.

        Thanks

            The closest I can find that has "similar Markings" (as in not the same pinout etc) is the HXD0113

            Renesas also makes a similar marked ic R2A20133DSP

            Do you have a picture of the back of your ic?

                Thank you R_J, very helpful info!
                I think is Renesas chip: RAA230152

                Now the problem is a source to buy

                Tonight will verify again the PCB according with that new info, then will search a provider for chip.

                Thanks again!

                  RAA230152GSB#HA0 (5v fixed output) https://www.chip1stop.com/view/dispD...t_RENE-0068885

                  This ic may be replaced by the RAA230153GSB#HA0 which is adjustable so you may need to add resistors to get the 5v output? (See page 18 for resistor values)

                  Maybe you can request a free sample from Renesas https://www.renesas.com/us/en/buy-sa...how_price=true
