MT7813

MT7813 High Efficiency High Precision Buck Constant Current Driver DESCRIPTION MT7813 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 MT7813 turns on the internal power MOSFET when the inductor current reaches zero, reducing the power MOSFET switching loss, the system achieves more than 95% efficiency. With critical conduction mode, and the input compensation, MT7813 outputs high accuracy LED current, and further achieves good line regulation and load regulation. MT7813 embedded with internal power MOSFET, simplify the peripheral circuits. Low BOM cost is achieved. MT7813 has wide working voltage range, which is suitable for full-range AC input or 10V-400V DC input voltage. MT7813 provides various kinds of protections, such as over current protection(OCP), short circuit p...
