iW3690 Datasheet | Dialog Semiconductor

Description The i W3690 is a single-stage, high performance AC/DC off-line power supply controller for intelligent LED luminaires. A master controller can municate with the i W3690 through the I2C bus interface to control the LED driver output current. With advanced digital control, the i W3690 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 i W3690 to sleep mode to achieve remote light off function at low standby power. The i W3690 uses Dialog’s proprietary Dual-Dim technology, which enables intelligent LED luminaires that are patible 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...
