PMP4484: 2 Channel instead of 6 channel with Auxiliary Power Supply 3.3V or 5V DC

Part Number: PMP4484

Hi Linda,

Thanks for your feedback. Please refer the attached pdf file. I have made changes in schematic as suggested by you. Please validate the same.

Also, I want to control dimming using WiFi or BLE or any other external RF-SOC. For this, I need 3.3V or 5V power supply. Is the auxiliary power supply is available in this design? If yes, can you help me to find out the pin from which I can take the 3.3V or 5V power out? If no, can I use LM2596 as buck converter to get it from 40Vout pin or do you suggest any other chip?

Thanks.

Best regards,

Amit
