Single - multichannel LED driver - strips, signage
Achieve top scalability, flexibility and cost efficiency
Both LED strips and multichannel LED applications require a constant voltage input, usually up to 60V. Commonly used in accent lighting, each LED string or channel needs an LED driver IC, usually, a linear LED driver IC for up to 250 mA LED current. Applications using linear LED driver ICs need a low voltage overhead of the IC so as many LEDs as possible can be stacked in series. This increases efficiency and reduces thermal overload on the LED board – two features the market demands.
Multichannel LEDs are the ideal choice when you require high light output combined with low output voltage, say below 60V. For such high current applications with switch-mode LED drivers, the key challenges are current accuracy, PWM and analog dimmability, and thermal protection. Turn to Infineon for the know-how and components you need to do so.
System overview for LED strips and multichannel LED applications
Infineon’s products for LED strips and multichannel LED
To design the best possible LED strip, look no further than our portfolio of high-quality, cost-efficient components. For LED driver ICs, at Infineon, we offer two main product families: BCR and ILD. The BCR series contain the smallest and most affordable products for linear LED driver ICs. The ILD series features DC-DC LED driver ICs that provide high efficiency as well as other interesting features, such as thermal protection. Both families come with a line-up of regulators with an integrated power stage and a line-up of controllers that allow the utmost scalability via flexible dimensioning of the output stage.
Explore our products for more details on how you can maximize LED strips and multichannel LED designs with Infineon.
The BCR linear LED drivers are perfectly suited for driving LED currents from 10 mA to 250 mA, making them the ideal choice for low- to mid-power LEDs in general lighting applications.
This represents the lowest-cost solution that requires an ultra-low external part count and PCB space. The light out- put can be adjusted via an external resistor. PWM dimming is supported either by a microcontroller interface or by means of an external digital transistor.
Thanks to its negative thermal coefficient, the LED load will be protected from overheating.
The new-generation BCR430U and BCR431U drivers feature an extra-low voltage drop and a smart temperature con-trolling circuit.
