Boost conversion in LED TV backlighting: addressing the challenges of efficiency and stability
The rapid evolution in TV technology has had a dramatic effect on the requirements of the power supply of consumer electronics devices. LEDs have become the preferred light source for the LCD backlight. In parallel, consumer demand has led TV manufacturers to increase production of large panel sizes. As a result, the power supplies for TV backlighting systems are required to drive very high numbers of LEDs in multiple parallel strings, supplying a high voltage output and a high load current.
