Dialog Semiconductor iW3640
The iW3640 is a two-stage, high-performance AC/DC offline power supply controller for dimmable LED luminaires. It applies advanced digital control technology to detect the dimmer type and phase, which provides dynamic impedance to interface the dimmer and control the LED brightness at the same time. The iW3640 uses Dialog’s unique digital FlickerlessTM technology to eliminate visible flicker in the entire dimming range and minimize low frequency output ripple current.| Part No. | iW3640 |

DESCRIPTION
The iW3640 drives two-channel outputs. The duty cycle of the second channel varies with the dimming ratio. With advanced dimmer detection technology, the iW3640 can operate with most wall dimmers including leading-edge dimmers (R-type or R-L type) and trailing-edge dimmers (R-C type). In addition, the iW3640’s cycle-by-cycle waveform analysis technology allows fast dimmer setting response. When no dimmer is on
