12 W LED downlight design features sophisticated dimming and color
management over Bluetooth using smartphone application

SAN JOSE, Calif.–(BUSINESS WIRE)–#PowerIntegrations–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 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.

is a Class 2 embedded Bluetooth 4.0 module designed for LED lighting
control applications, light fixtures and LED bulbs. It is pre-programmed
with Casambi’s proprietary firmware, making it completely compatible
with other Casambi enabled devices. CBM-001 is controlled wirelessly
with Casambi smartphone and tablet applications using the Bluetooth 4.0
protocol. Devices automatically form a self-healing and self-organizing
wireless mesh network so that a large number of fixtures can be
controlled from any point. No external gateway module is needed.

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.”

Adds Timo Pakkala, CEO and co-founder at Casambi: “The Power
Integrations InnoSwitch-CH power supply controller has excellent
efficiency, particularly at light load. This allows our module to
operate continuously and effectively, resulting in a great user
experience with high performance and scalability.”
