Maximizing IC Performance
MT7844
Non-isolated APFC BUCK LED Driver
DESCRIPTION
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 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 protec...
