iW3690

iW3690 AC/DC Advanced Digital Power Controller for Phase-Cut Compatible I2C Digital Dimming LED Drivers 1 Description The iW3690 is a single-stage, high performance AC/DC off-line power supply controller for intelligent LED luminaires. A master controller can communicate with the iW3690 through the I2C bus interface to control the LED driver output current. With advanced digital control, the iW3690 regulates a constant current to an LED load over a 1% to 100% dimming range without flicker or shimmer. The driver can support either wired or wireless links via the master controller. Moreover, the master digital controller can set the iW3690 to sleep mode to achieve remote light off function at low standby power. The iW3690 uses Dialog’s proprietary Dual-Dim technology, which enables intelligent LED luminaires that are compatible with wall dimmers while offering superior performance. When a wall dimmer only is used, the LED driver output current is controlled based on the phase conductio...
