AF1820 Product details

Description

The AF1820 is a TRIAC and multi-steps dimmable simplest current injected topology control IC for isolation LED driver that had some characteristics, the first is operating without electrolytic capacitors which is necessary for the DC power supply structure, the second is operating without photo coupler and the last is enhancing the power factor to larger than 90%.

Features

Without electrolyte capacitor No photo coupler PWM frequency jittering to reduce EMI noise HV Start-up circuit eliminates outer resistor and reduce input power consumption Constant current (RMS) for LED Phase-controlled TRIAC Dimming Multi-steps dimming Integrated Over Current Protection (OCP) Embedded Leading Edge Blanking (LEB) Integrated Over Voltage Protection (OVP) Integrated Thermal Shutdown (TSD) System efficiency >90% in simulation System PF >0.9 in simulation.
