Descriptions
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.
Applications
LED lighting
