Tel：886-3-5645656 Fax：886-3-5645626 DR264-12 DR264-12 2 Segment String LED Open Reactivate IC with 0.2V voltage drop General Description The DR264-12 is a 2 segments open reactivate IC, designed for protecting continuous current switching mode inductive buck LED lighting systems. If any LED in the a continuous current switching mode inductive buck LED lighting system broke down and leave the system open, the DR264-12 will take the place of the LED that broke down and reactivate the entire string of LEDs while consuming less voltage drop than an average LED. The maximum bypass current value of DR264-12 in is 1A. The DR264-12 also provides low voltage drop with 1A bypass current. Built-in OVP and reverse connection protection circuits to avoid protector and LED burnt out. Features z 2 serial bypass segments z Maximum bypass current: 1 A z The voltage drop of one bypass segment at 1A bybass current: 0.2V z The total voltage drop of all segments simultaneous bypass at 1A bybass current: 1.6V (only for TO-252 package) z Reverse protection current of TO-252 package: 1A z Reverse protection current of SOT-23 package: 400mA Applications z LED string lighting Package Types z SOT-23; TO-252 2 ...
