STMicroELectronics launched 3 LED backlight and lighting for a single block boost converter, models were LED7706, LED7707 and PM6600.
In 30mA or 85mA current, the boost converter can drive 6 rows of 10 white LED. LED7706, LED7707 and PM6600 optimized for mobile devices including chip MOSFET to reduce the number of parts. Work up to 1MHz to minimize filter elements.
30mA LED7706 and 85mA output voltage of 36 volts, the single chip solution used in the LCD panel can reach up to 17 inches (LED7707). External sync pins can be used to connect additional devices to larger sizes. The LED7707 output of the 85mA also meets the individual LED lighting applications.
PM6600 is the PM66xx series of STMicroelectronics company, providing a complete NB power management solution. 6 + 36 constant 30mA current channels can be applied to large notebook sizes. Like other two products, PM6600 has a sync pin to work under the larger display screen.
Three products with energy-saving mode and PWM dimming. Each device has a ceramic output capacitor to reduce material costs. In addition the built-in anti overheating. Output over voltage and over current protection of MOSFET. 24 pin VFQFPN package size of 4 x 4mm. Software startup function. Maximize backlight life.
Prices, LED7706, LED7707, PM6600 are 1000 as a wholesale unit, the price was $1.80, $1.90, $1.80.
