Overview
Description
The iW3636 single-stage LED driver is a dimmable digital offline PWM controller for solid-state lighting applications up to 90W with high power factor (PF >0.9) and low THD (<20%). The device offers a dedicated PWM dimming input, which allows the iW3636 to work with a wide range of dimming interfaces including wireless modules, MCUs and 0-10V interfaces. A unique feature internal to the iW3636 compensates for non-linear optocoupler delays for isolated dimming applications. And, the iW3636 has a full 1% to 100% dimming range, with the minimum dimming setting configurable to dim-to-off, 1%, 5% or 10%.
The iW3636 can be paired with Renesas' iW339 3-in-1 dimming interface controller, which integrates the current source and optocoupler driver to provide a low BOM cost, simple solution for dimmable commercial T8, external and fixture driver lighting applications, including wireless and intelligent LED lighting.
