High Efficiency High Precision Buck Constant Current Driver
DESCRIPTION
MT7814BD 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.
Critical conduction mode ensures that the MT7814BD 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, and the input compensation, MT7814BD can achieve precise output current and excellent line regulation and load regulation.
MT7814BD embedded with internal power MOSFET, it can achieve simplified peripheral circuits and low BOM cost.
MT7814BD has wide working voltage range, which is suitable for full-range AC input. MT7814BD provides various protection features to improve the system reliability, including over current protection (OCP), short circ...
