LC5545LD Overview
Key Specifications
Package: DIP
Mount Type: Through Hole
Max Voltage (typical range): 20 V
Max Operating Temp: 125 °C
Description
The LC5540LD series are isolated LED drivers in which a power MOSFET and a control IC are highly integrated. The IC provides the systems that can comply with the harmonics standard (IEC61000-3-2 Class C) in all conditions, including a light load condition.
Key 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 Pin Capacitor)
- Leading Edge Blanking Function
- Built-in Maximum On-time Limitation Function
