AF1820 - Without electrolyte capacitor Offline LED Controller
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 coup
AF1820 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) Embed
