Power Integrations, an expert in high-efficiency, high-reliability LED-driver ICs, and Casambi Technologies OY 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.
