Infineon has introduced a low-cost IC specifically designed for driving high-power LEDs. The BCR 450, in combination with an external transistor, features highly precise current control, thermal protection as well as over-voltage and over-current protection functions. As the chip produces no electromagnetic radiation, it is well suited for applications sensitive against electromagnetic interference (EMI), such as lighting in transportation vehicles including buses, ships, trains and aircrafts, as well as medical applications with communication bus systems. In addition to general lighting systems, it is also suitable for applications in architectural and accent lighting, advertising, strobe lights for emergency vehicles, hazard lights and road safety lights.
The BCR 450 was specifically designed for use with high-wattage LEDs in the 0,5 W, 1 W and 3 W ranges in combination with an external transistor. By simply changing the external transistor, manufacturers of LED lighting have the flexibility to adapt output currents from 100 mA to above 1 A. Since there is no need for capacitors, the lifetime of the LED system can be extended.
In large parts of the illumination market and especially in architectural lighting a homogenous light output in the whole LED chain of light sources is crucial, since the human eye is very sensitive to shifts in light colour. The BCR 450, with its output current precision varying only ±10% over the entire operating temperature range, supports the homogenous light output requirement for LED lighting fixtures.
