0-10V dimmable LED driver

The iW3630 offers an output power up to 45W, high power factor (PF) > 0.95, total harmonic distortion <15%, and a small BOM to address performance, cost and reliability issues in high-performance, dimmable commercial solid state lighting applications.

The iW3630 features a built-in isolation transformer driver that enables direct, 0-10V dimming without the need for an additional driver circuit and microcontroller. It also incorporates Dialog's proprietaryPrimAccurate™primary-side control technology, further reducing the BOM count by eliminating the need for an opto-coupler and external compensation components.

Incorporating Dialog's proprietaryFlickerless™technology, the iW3630 allows for full 1%-100% flickerless dimming using either a direct analog voltage or a PWM signal. It is feature rich to ease design and provide a very robust solution, integrating Dialog’s EZ-EMI® technology and several protection features, including LED over-temperature protection.
