Power Integrations, the leader in high-efficiency, high-reliability LED-driver ICs, and Casambi Technologies OY, today announced a new reference design, DER-612, describing a constant-voltage (CV), constant-current (CC) 12-watt isolated flyback power supply with power factor correction for smart lighting applications. The design includes a 3.3 V power supply to drive a Casambi CBM-001 Bluetooth® wireless module, which provides convenient dimming and color management control of the four-string LED load from 0 mA to 400 mA. The power supply operates over a universal input voltage range of 90 VAC to 265 VAC and achieves greater than 0.8 power factor across all line conditions.
Comments Hubie Notohamiprodjo, director of product marketing for LED lighting at Power Integrations: "Smart lighting systems monitor and control sophisticated home and workplace lighting installations. The standby power needed for the control subsystem often negates any savings that high efficiency LEDs offer. Casambi’s low quiescent current draw combined with the very low standby consumption of InnoSwich-CH optimizes standby performance while maintaining instant light availability."
