PLANO, Texas–(BUSINESS WIRE)–Diodes Incorporated (Nasdaq: DIOD) today announced the introduction of
the AL1665 single-stage, fly-back and buck-boost controller for
commercial, connected, and dimmable LED lighting installations operating
at up to 100W.
The AL1665 is designed to drive an external MOSFET to control LED loads
and maintain a high power factor. It provides a compact and efficient
solution that helps minimize the use of additional components and
maintains high switching efficiency.
Designed to operate from an AC input voltage of between 85VAC and
305VAC, the AL1665 utilizes primary side regulation (PSR) topologies,
removing the need for optical isolation or secondary side control. With
PSR, developers can design smaller solutions using less PCB area and
achieve lower bill of material costs, while delivering constant current
regulation to high-power LED lighting applications.
The ability to apply dimming across 0.5% to 100% of the high-power
output makes the AL1665 suitable for commercial LED applications where
the lighting output levels need to be adjustable to save power, or for
aesthetic purposes like in retail displays. Compatible with
ANSI-approved dimmers, the output voltage can be adjusted between 0V and
10V using a dedicated PWM input, or with an analog input voltage of
between 0V and 2.5V, making it simple to develop connected lighting
systems that can be managed both locally and remotely.
The device employs boundary condition mode (BCM) conversion with valley
switching to minimize losses and deliver high efficiency with low EMI.
The wide supply voltage allows the AL1665 to operate in any geographical
region directly from the main supply, while its line and load regulation
of less than ±2%, power factor of more than 0.9, and THD of less than
20% enables manufacturers to comply with all relevant legislation.
The AL1665 is available in the SO-8 package. Further information is
