The MSL2164 and MSL2166 16-string LED drivers with integrated timing algorithms improve picture quality of LCD TVs by eliminating 3D ghosting and flickering effects. The parts include 12-bit PWM string dimming, which allows 4,096 gray scales for an enhanced image.
Both driver use external current control MOSFETs to sink up to 350 mA per string, with matching better than ±0.8%. Additional features include 8-bit global intensity dimming, 12-bit PWM string phrasing, 10-bit digital-to-analog converter (DAC) current control, which increases dimming control in lower light conditions, and 8-bit adaptive power correction, which maximizes efficiency of up to 3 string power supplies. In addition they offer fault detection and management of open- and short-circuit LEDs and a 20-MHz SPI serial interface. ($5.95 ea/1,000 — available now)
