Infineon Adds LED Drivers To Energy-Saving Range
Infineon Technologies AG is extending its portfolio of energy-efficient lighting ICs with a range of low-cost linear LED drivers. The BCR320 and BCR420 product ranges address the market for energy-saving and environmentally friendly light-emitting diode (LED) lighting solutions. Designed for driving 0.5W LEDs with a typical current of 150 to 200mA, these LED drivers feature a negative thermal coefficient, contributing to a long lifetime of LEDs and a digital interface for a pulse-width modulation (PWM) signal for dimming. The BCR320 and BCR420 LED drivers are tailored to address deficiencies for 0.5W LED applications, providing a low-cost solution with a small form factor. With both devices, the use of inductors, capacitors and free-wheeling diode can be avoided. The elimination of electrolytic capacitors can also contribute to the extended lifetime of the LED system. The BCR320 products are designed for a peak output current of up to 300mA. For continuous operation, a maximum nominal...
