MT7822 High Efficiency Buck Constant Current LED Driver DESCRIPTION MT7822 is a high precision LED constant current control chip 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. Critical conduction mode ensures that the MT7822 turns on the internal power MOSFET when the inductor current reaches zero, reducing the power MOSFET switching loss, and achieving more than 95% efficiency. With critical conduction mode, MT7822 outputs high accuracy LED current, and further achieves excellent line regulation and load regulation. It’s insensitive to inductance and the I-shape inductor can be used.
