MT7817BD PWM/Analog dimmable Non-isolated Constant Current LED Driver DESCRIPTION MT7817BD is a high precision LED constant current controller operating at critical conduction mode (CRM) with zero current switched-on and peak current switched-off. It’s mainly targeted for non-isolated buck LED power systems and PWM/Analog dimmable application. Critical conduction mode ensures that the MT7817BD turns on the internal switch when the inductor current reaches zero, reducing the switch-on switching losses, and achieving more than 93% efficiency. With critical conduction mode, and the input compensation, MT7817BD outputs high accuracy LED current, and further achieves excellent line regulation and load regulation.
