  MT7910 High Brightness LED Driver DESCRIPTION The MT7910 is a hysteresis current mode control LED driver IC. The MT7910 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 MT7910 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. It also includes a 0 - 245mV linear dimming input which can be used both for linear dimming and temperature compensation of the LED current. The MT7910 is ideally suited for buck LED drivers. Since the MT7910 operates in hysteresis current mode control, the controller achieves good output current regulation without the need for any loop compensation.
