Maximizing IC Performance MT7844D Non-isolated APFC BUCK LED Driver DESCRIPTION The MT7844D 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.
MT7844D works in Quasi-Resonant Mode (QRM), which improves both of efficiency and EMI performance.
The system integrates the ultra-high voltage power supply circuit, the start-up resistor and power supply diode are not needed.
Low external component count and cost is achieved.
Various protections such as over voltage protection (OVP), over current protection (OCP) and over temperature compensation, etc.
are embedded to improve reliabilit...
