Overview

MT7828 High Efficiency Buck Constant Current LED Driver DESCRIPTION MT7828 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 MT7828 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, MT7828 outputs high accuracy LED current, and further achieves excellent line regulation and load regulation.
It’s insensitive to inductance and the I-shape inductor ...
