Description
The LC5546AD and LC5546LD are isolated LED drivers in which a power MOSFET and a control IC are highly integrated.
Features
- the IC can provide and more cost-effective power supply systems with fewer external components. Features.
- Built-in On-time Control Circuit (High Power Factor Achieved by Average Current Control).
- Built-in Startup Circuit (Reduced Numnber of External Components).
- Soft Start Function (Startup Stress Reduction for Power MOSFET and Secondary Rectifier Diode).
- Bias Assist Function (Improved Startup Performance, VCC Voltage Drop Suppresion in Operation, Reduced Capacitance of VCC.
