ON Semiconductor has revealed a single channel LED driver tuned for low power applications, electronicsweekly.com reports.
Using a patented architecture and integrating fault protection and fault diagnostics, the CAT3661is able to drive a single LED backlight with a current of up to 5mA.
The new device is ideal for use in equipment powered by coin cell batteries because of soft-start current limiting and short-circuit protection. Applications for the driver include low power backlighting for LCDs as well as backlighting for a wide range of portable handheld devices, the manufacturer explained.
Meanwhile, sales of packaged LEDs and solid-state lighting products are on the rise at Philips Lighting.
The company reported that LED-based sales grew 27 per cent in the first quarter compared to the first quarter in 2010 - representing 14 per cent of total lighting sales.
