Exclara’s newest solution, HVX (high-voltage LED driver) is a family of semiconductor devices designed to enable lowest total cost-per-watt while maintaining high performance. The EXC100 is the first product in this family and is a single-chip power supply for high-voltage LEDs. This lowest-cost driver supports low parts count. For example, a 10W power supply only requires 10 to 15 components including the PCB. By integrating all control functionality required for high-voltage AC operation it enables less expensive solutions than the DC solutions. This also allows a smaller overall power system. The HVX family offers high efficiency, high power factor, and low EMI with maximum reliability and long life, all with a plug and play design.
Combination of small form factor and excellent electrical performance makes the EXC100 ideal for T-style linear tubes and also lamp-style applications where the entire power supply using a 7x7 mm QFP EXC100 IC can be integrated into the LED subsystem.
The EXC100 supports operation either directly from AC line or from dimmers, making it an excellent drop-in choice. HVX-based systems do not require use of an electrolytic capacitor and therefore can match the operating life of LEDs.
An HVX-based LED light bulb solution can be built in high volume enabling mass market price under $10. With significantly longer life and lower power consumption compared to other technologies such as incandescent, this price point is driving an inflection point in the high volume adoption of LED-based lighting.
Exclara HVX products enable:
LED bulb without transformer, electrolytic capacitors or bleeder load
High energy savings through efficient power conversion techniques
High power factor for minimum energy loss in the power grid (compliant with the most demanding of worldwide utility companies)
Low EMI pollution below legal limits across the world
