MXT7261

MXT7261 Primary Side Feedback Single-stage Active PFC LED Driver IC Description Features MXT7261 is a single-stage, with the source power z Single stage cascade, source power factor factor correction, high-precision primary side adjust, high PF value, low THD feedback LED constant current control IC, which z Primary feedback constant current control, can be applied to 85Vac-265Vac full range input no need secondly feedback circuit voltage flyback isolated LED constant current z Very high speed to LED start up(<200ms powerThis controller integrates active power @85Vac) factor correction circuit, which can achieve high z ±3% LED output constant current precision power factor and low total harmonic distortion. z Excellent linear voltage adjust rate and load Due to operating in inductor current critical voltage adjust rate continuous mode, power MOS transistor is at z Inductance current critical continue mode zero current turn on condition, the switching loss z Source drive mode can be reduced, while the utilization of z Very low (20Ua) start up current transformer can be increased. z Very low (600uA) work current MXT7261 uses a proprietary current sampling z FB feedback resistance value is high, low system with the primary feedback mode，which power can achieve high precision output constant z LED short / open circuit protection current control without secondary feedback circuit, z Current samples collect resistance short / so it can not only s...
