MT7812 Description

MT7812 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 MT7812 turns on the internal power MOSFET when the inductor current reaches zero, reducing the power MOSFET switching loss, the system achieves more...
