iW3640 Datasheet AC/dc Digital Power Controller

Manufacturer: Dialog Semiconductor (now Renesas)

Overview: iW3640 AC/DC Digital Power Controller for Two-Channel High Power Factor Dimmable LED.

General Description

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.
