DESCRIPTION

The MT7842 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.

MT7842 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 reliability. The MT7842

integrates 550V MOSFET, which further

simplifies external circuit.

FEATURES



Single-stage active power factor correction

(PFC > 0.90)
