Power Integrations and Casambi Technologies Showcase
Power Integrations (Nasdaq: POWI), 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.

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.
The design is based on Power Integrations’ InnoSwitch™-CH power supply controller, which combines primary, secondary and feedback circuits in a single surface-mounted offline flyback switcher IC. The IC incorporates the primary FET, the primary-side controller and a secondary-side synchronous rectification controller. The device also includes Power Integrations’ magneto-coupling communications technology, FluxLink™, which safely bridges the isolation barrier and eliminates the need for an optocoupler. Secondary-side control enables highly accurate constant-voltage regulation and an ultra-fast step load response while simple PWM control eliminates the need for a secondary DC/DC regulator. The high efficiency and very low standby power of the IC eliminates the need for additional heatsinks and enables customers to create solutions that meet demanding DOE-6 regulations. A built-in secondary-side auxiliary power output supports RF and MCU control circuitry.
