LED Drivers for LCD Backlights

LCDs are finding their way into an increasing number of devices, from mobile phones to portable audio players and printers. ROHM offers a wide array of LED drivers for LCD backlights, including models capable of driving 96 lamps, units with integrated dimmer for lower power consumption, RGB/Flash drivers, and ICs with built-in LDO that contribute to greater miniaturization. In addition, both chopper and charge pump types are offered for high efficiency and low noise operation, respectively.
