MT7844 driver equivalent, non-isolated apfc buck led driver.
* Single-stage active power factor correction (PFC > 0.90)
* Ultra-high voltage power supply without start-up resistor a.
The MT7844 is a high-PF, non-isolate LED Driver IC. The floating-ground, high-side BUCK topology makes full wave detection possible. High precision output current is achieved. MT7844 works in Quasi-Resonant Mode (QRM), which improves both of efficien.
