The application of the iML8683 is configured in - Compact size to minimize mechanical cost. parallel with an LED string. The iML8683 can work - Driver-on-board and chip-on-board available which as voltage controlled current source, current minimize process flow and assembly cost. regulator, or cut-off. It is suitable for the applications - High PF and Low THD performance. adopting periodical AC voltage source. - High efficiency achieved. The PCB layout is also very flexible to meet - Flexible PCB layout style. various shape requirements. It is especially suitable - Wide range of LED forward voltage selection. for replacing incandescent light bulb and linear type - Distributed heat to several chips. fluorescent lamp. - TRIAC dimmable. Chip - 88V input sustaining voltage. - <3V dropout voltage for up to 150mA regulating current Typical Application Circuit Applications AC LED lighting engine. LED light bulb. V AC LED1 LED light tube.
