A9912

AiT Semiconductor Inc. www.ait-ic.com A9912 AC-DC LED DRIVER 85~265V AC INPUT LED CONSTANT CURRENT DRIVER DESCRIPTION FEATURES The A9912 is a high voltage buck control IC for constant LED current regulation. The A9912 operates constant off-time mode. It allow efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 8VDC up to 450VDC or 110VAC/220VAC. The A9912 includes a PWM dimming input that can accept an external control signal with a duty ratio of 0~100% and a frequency of up to a few kilohertz, and the dimming also accept a 0~1.2V linear input signal. The RNTC pin can accept a 0~250mV Line Dimming input witch be used for temperature compensation of the LED current. The A9912 is available in SOP8 package.
