MT7900 High Brightness LED Driver DESCRIPTION The MT7900 is a hysteresis current mode control LED driver IC. The MT7900 operates in constant off-time mode. It allows efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 14VDC up to 450VDC or 85VAC ~ 265VAC. The MT7900 is ideally suited for buck LED drivers. Since the MT7900 operates in hysteresis current mode control, the controller achieves good output current regulation without the need for any loop compensation. Further, with Maxic proprietary control technology (patent pending), MT7900 achieves precision output current accuracy from 85VAC ~ 265VAC. Frequency jittering is used to reduce the EMI. TYPICAL APPLICATION CIRCUIT FEATURES • Proprietary constant-current control. Great LED current accuracy.
