AF1821 Product details

Description

The AF1821 is a TRIAC dimmable, primary-side-control offline LED lighting controller which can achieve high power factor and flicker-free TRIAC dimming output LED current for an isolate lighting application in a single stage converter.

Features

over-voltage protection, short-circuit protection, cycle-by-cycle current limit, VCC UVLO and auto-restart over temperature protection. The AF1821 is available in a small SOP-8 package. Features Real Current Control Without Secondaryfeedback Circuit Flicker-free Phase-controlled TRIAC Dimming Accurate Constant Current Output Boundary Conduction Mode Operation Ultra-low (10µA) Start Up Current Low (1mA) Quiescent Current Input UVLO Cycle-by-cycle Current Limit Over-voltage Protection Short-circu.
