DIO8244 - Adaptive 100/120Hz Current Ripple Remover

Datasheet Summary

Description

DIO8244 is a regulator for driving internal NMOSFET to remove the 100/120Hz LED string current ripple on AC/DC power.

Patented control strategies are optimized for remover current ripple.

Nover circuit design makes a lower BOM and high cost-effective for flickerless filament.
