Could you suggest a circut to drive 72 led at 100mA using CCR (NSIC50xx) family (non isolated) which can be driven on 230V AC. There are not any reference for 230Vac driven CCR circuit. Even your latest design note DN05021 / DN05022 does not specify how to drive at 230V AC. Also datasheet for NSIC5020 is missing.\n\nHemant Savla

For an offline 230VAC application we can suggest to use capacitive drop drive topology with a constant current regulator to drive LEDs: http://www.onsemi.com/pub_link/Collateral/AND8492-D.PDF an application note with four examples. The part number NSIC5020 is not a valid part. Please refer to our CCR’s portfolio at: http://www.onsemi.com/PowerSolutions/se ... ype=others \nThank you. Answered by:
