Description: On-Bright Confidential to EUCHIPS OB366 3 Dimmable Flyback PSR Controller GENE RAL DESCRIPTION The OB3663 is a high pe rformance single stage AC/DC fly-back c ontroller for dimmable LED luminaires. The OB3663 integrates advanced digital processing core to eliminate visible fl icker. OB3663 offers fast startup featu re, constant on-time control for power factor correction (PFC), zero current d etector (ZCD) to ensure transition mode (TM) operation, and accurate current r egulation. OB3663 offers comprehensive protection coverage including VDD under voltage lockout (UVLO), VDD over volta ge protection, load voltage over voltag e protection, cycle-by-cycle current li miting, over temperature protection,
