Intersil’s new ISL9767x LED driver family could extend battery life in notebook, netbook, and tablet computers, which droved up to six 40mA strings of LED Linear high bay light and delivered 0.7% current matching between strings. The design reduces flickering, shimmering, and banding backlight. The key to efficient low-level dimming was an adaptive boost control circuit, which kept dimming linearity even when the LEDs were off for most of the PWM duty cycle. The drivers could dim LEDs to 0.007% of full brightness.
Linear Technology’s new LTM8042 family could withstand 40V input transients in backlight applications and rugged environments. The LTM8042 and LTM80420-1 μModule drivers could power strings of 8 white LEDs or 9 red LEDs. PWM-based dimming offered a 3000:1 ratio. The drivers could operate in buck, boost, or buck-boost modes and offer 0.5% line regulation along with the aforementioned transient protection. The LTM8042 sources 1A of current while the LTM8042-1 sources 350 mA.
Executive Vice President of Jiangxi Changda comments, “I have been impressed with the reputation of this equipment thus our team has been looking forward to the arrival of the new led high bay light reactors. We need them to comply with our planned capacity increase as we manufacture more LEDs to meet the strongly growing demand. The AIXTRON systems match our specification for process flexibility, thickness uniformity, doping, and composition. We had a swift and efficient installation thanks to the AIXTRON close local support and service.”
