MT7811B
High Efficiency High Precision Buck Constant Current Driver
DESCRIPTION
MT7811B 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 MT7811B 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, MT7811B can achieve precise output current and excellent line regulation and load regulation.
