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 conduction angle of the dimmer. This same information is used to set
the high limit of the LED current when a digital dimming command is received from the I2C bus. While the I2C bus has
priority over the wall dimmer, the iW3690 can respond to both dimmer interfaces at the same time, allowing the driver
to enter a stable sleep mode state at any wall phase conduction angle. Dialog’s Dual-Dim technology allows the light
output to be dimmed to 1% without flicker.
The iW3690 offers all the advanced features of Dialog’s industry leading phase-cut dimming technology, including high
efficiency and superior dimmer compatibility at low BOM cost. The iW3690 offers high performance, a wide dimming
range and excellent dimmer compatibility while minimizing the external component count through high system-level
integration. Dialog’s EZ-EMI® technology works to simplify the input EMI filter, further reducing circuit size and cost
while providing excellent noise rejection capability to AC line distortions.
