IML8684BP-ADJ-TR [EXAR]

The iML8684 is a Three Terminal Current Controller (TTCC) for regulating the current flowing through an LED string. The application is configured in parallel with an LED string and can work as a voltage-controlled current source, current regulator, or cut-off. It is suitable for applications adopting periodic AC voltage sources. The PCB layout is flexible to meet various shape requirements, especially for replacing incandescent light bulbs and linear fluorescent lamps. Features include all solid-state components, no electrolytic capacitor required, compact size, driver-on-board and chip-on-board availability, high PF and low THD performance, high efficiency, flexible PCB layout, wide LED forward voltage selection, distributed heat dissipation, and TRIAC dimmability. The chip sustains 88V input and has <3V dropout voltage for up to 150mA regulating current.
