A9910

AiT Semiconductor Inc. www.ait-ic.com A9910 AC-DC LED DRIVER UNIVERSAL HIGH BRIGHTNESS LED DRIVER DESCRIPTION FEATURES The A9910 is a PWM high-efficiency LED driver  >90% efficiency control IC. It allows efficient operation of  10V to 600V input range high-brightness (HB) LEDs from voltage sources  Constant-current LED driver ranging from 10VDC up to 600VDC. The A9910  Applications from a few mA to more than 1A controls an external MOSFET at fixed switching output frequencies up to 300kHz. The frequency can be  LED string from one to hundreds of diodes programmed using a single resistor. The LED string  Linear and PWM dimming capability is driven at a constant current rather than a constant  Input voltage surge ratings up to 600V voltage, thus providing a constant light output and an  Available in SOP8 Package enhanced reliability. The output current can be programmed between a few milliamps and up to APPLICATION more than 1.0A. The A9910 uses a rugged high-voltage junction isolated process that can  DC/DC or AC/DC LED driver applications withstand an input voltage surge up to 600V. The  RGB backlighting LED driver output current to a LED string can be programmed to  Backlighting of flat panel displays any value between zero and its maximum value by  General-purpose constant current source applying an external control voltage at the linear  Signage and decorative LED lighting dimming control input of the A9910. The A9910  Automotive provide...
