Infineon - BCR601 and BCR602 – 60 V linear LED controller ICs

Infineon – BCR601 and BCR602 – 60 V linear LED controller ICs

BCR601 is a linear LED controller IC regulating the LED current with an external driver transistor. It supports either NPN bipolar transistors or N-channel MOSFETs to cover a wide LED current and power range up to several amperes. The LED current is fully scalable by dimensioning an external resistor at MFIO pin.

The BCR602 is a perfect fit for 48V LED applications by combining small form factor with low cost. Through its higher integration, BOM savings and ensuring long lifetime of LEDs, this controller has many advantages compared to discrete solutions.
