Sanken LC5545LD
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. These systems, moreover, can be achieved without an input electrolytic capacitor.| Part No. | LC5545LD |

DESCRIPTION
The IC employs the average current and quasi-resonant controls: the average current control realizes high power factors, whereas the quasi-resonant control contributes to high efficiency and low noise. Having a rich set of protection 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 Pin Capacitor)
● Leading Edge Blanking Function
● Built-in Maximum On-time Limitation Function
● Protections Include: Overcurrent Protection (OCP): Pulse-by-Pulse Overvoltage Protection (OVP): Latched Shutdown Overload Protection (OLP): Latched Shutdown Thermal...
