Overview

MT7897 TRIAC Dimmable Constant Current LED Driver DESCRIPTION MT7897 is a high precision LED constant current controller.
It operates in critical conduction mode (CRM) with zero current switched-on and peak current switched-off.
It’s mainly targeted for BUCK-BOOST LED power systems.
MT7897 supports high power factor application.
The Power Factor (PF) can reach 0.
8 or higher.
CRM ensures that the MT7897 turns on the internal power MOSFET when the inductor current reaches zero, reducing the power MOSFET switching loss.
With critical conduction mode, and line compensation, MT7897 outputs high accuracy LED current, and further achieves excellent line regulation and load regulation.
