Introduction
MT7842 is a high power factor, non-isolated LED driver IC. It achieves full-cycle sensing through a floating ground, high-side sensing, buck switching power supply architecture. With an internally integrated high-voltage supply circuit, MT7842 eliminates the need for start-up resistors and supply diodes, reducing overall cost. MT7842 operates in quasi-resonant mode, improving both efficiency and EMI performance. Additionally, through an internally integrated selectable maximum period control mode, it eliminates power-frequency flicker while ensuring sufficient demagnetization time. MT7842 integrates multiple protection features, including OVP, OCP, over-temperature compensation, and more, enhancing reliability. All protections are self-recovering. The built-in 550V high-voltage MOSFET simplifies the peripheral circuitry.
Features
- Single-stage power factor correction (PF >0.9)
- High-voltage supply, no startup or auxiliary power circuit required
- High-precision LED output current (±3%)
- Excellent line and load regulation (±2%)
- Quasi-resonant operation mode
- Multiple protection features
- SOP7 package
Applications
- E14/E27/PAR30/PAR38/GU10 luminaires
- T8/T10 LED tubes
- Other LED driver applications
