DESCRIPTION
High precision output current is achieved. MT7844D works in Quasi-Resonant Mode (QRM), which improves both of efficiency and EMI performance. 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 MT7844D integrates 550V MOSFET, which further simplifies external circuit.FEATURES
● Single-stage active power factor correction (PFC > 0.90)● Ultra-high voltage power supply without start-up resistor and power supply diode
● High accurate LED current (±3%)
● Good Line and Load Re
