LC5546AD Datasheet Led Driver Ic

Manufacturer: Sanken

Overview: No Input Electrolytic Capacitor Required, IEC61000-3-2 Class-C Isolated LED Driver IC LC5546AD/LD Data.

General Description

The LC5546AD and LC5546LD 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.

These systems, moreover, can be achieved without an input electrolytic capacitor.

Key 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.
