Diodes Incorporated Intros New Power Factor-Corrected AC-DC LED Driver
Diodes (News - Alert) Incorporated, a manufacturer and supplier of application specific standard products serving the broad discrete, logic and analog semiconductor markets, has launched the AP1684, a power factor-corrected AC-DC LED driver that can be used with various types of offline LED lamps like E26, GU10, PAR and T8.
The AC-DC LED driver leverages pulse-frequency modulation technology and operates in boundary-conduction mode. The current regulation that the device delivers is accurate to a degree of ±2 percent. It can also achieve a power factor of .97 and THD of less than 20 percent, said officials.
This primary-side driver has been designed to reduce bill-of-materials cost as it eliminates the need for additional opto-coupler, secondary-side control and loop-compensation circuitry. The AP1684 uses an external bipolar junction transistor and needs only a small external component count.
Its SO-8 packaging and type of construction allows lamp designers to reduce PCB footprint and also enhance power density and product reliability.
High efficiencies are ensured by the device owing to its low start-up and operating currents. It also uses dynamic base driver control and valley-mode switching for reducing the transition loss besides boosting efficiencies to as high as 93 percent. Also the AP1684’s features over-voltage, short-circuit and over-temperature capabilities for protecting the circuitry.
These features make the device suitable for several applications in consumer electronics, computing, communications, industrial, and automotive applications. The product group includes diodes, rectifiers, transistors, MOSFETs, protection devices, functional specific arrays, single gate logic and amplifiers.
Discrete diodes are defined as the basic building block of an electronic circuit. They are designed to allow current to flow in only one direction to prevent damage to the circuitry system.
These electronic components used in myriad applications ranging from automotive, telecommunications and electronics are expected to witness steady growth in the coming years according to a research report titled “Discrete Diodes: A Global Strategic Business Report” published by Global Industry Analysts.
