VISHAY Intertechnology, represented in Australia by Braemac , has released a fully integrated universal constant-current control one and two-channel LED driver. It includes all necessary components in a single package.

The FunctionPAK FX4040G7xx is optimised to provide high efficiency in driving power LEDs in a range of lighting applications. It delivers adjustable current control from 0A to 2A at fixed power supplies up to 35V. It has a 10mm x 10mm x 2.8mm package. The driver's nine-port BGA package is rated for a full industrial temperature range of -40°C to +85°C, enabling the device to satisfy stringent ambient temperature requirements.

The FX4040G7xx drives power LEDs rated for up to 2A when connected with a low-voltage source such as a battery and it ensures the full load life of the LED without exceeding the applicable LED voltage. The driver's two independent channels allow two LED lines to be controlled by one module. Each of channels has an output power of 60W and maximum current of 2A.

The current-control driver provides designers with the flexibility to use various battery configurations and chemistries (NiCd, NiMH, or Li+) and fixed power supplies with input voltage ratings of up to 35V. External resistors may be used to adjust the constant output current to various LED configurations.

The FX4040G7xx integrated universal current-control driver serves as a ready-to-use LED driver solution for use in end products including bike lamps, headlamps, flashlights, medical instrumentation, general and emergency alarm lighting, design and architectural lighting, interior and runway lights, outdoor accent lighting, household appliances, and other systems requiring a small design. Because no external components are required, the engineering, testing, and assembly processes are simplified. As a result, both production costs and time to market are reduced.
