AC step driver increases design flexibility for LED lighting
Unlike conventional AC driver solutions which use a single large driver, iML has patented a novel distributed architecture of multiple small, low cost drivers. The solution provides increased flexibility and a lower overall BOM cost as it uses much lower voltage technologies. The solution also improves heat dissipation as multiple devices are used across the PCB, evenly distributing the thermal load. IML devices remove the need for electrolytic capacitors and inductors that are mandatory for AC-DC driver solutions while delivering lower BOM costs.
The iML8684 offers improved circuit stability in sub 3-volt AC situations created by TRIAC dimming, resulting in superior light quality at low dimming. The improvement also increases the number of compatible dimmers in both 120 VAC and 230 VAC countries.
Availability and Pricing
The iML8684 device is currently available in DFN2x2-6L and SOT-89-5L packages. Pricing starts at $0.18 in 10,000 unit quantities.
