ULD5121 Datasheet (UTC) - ADAPTIVE 100/120Hz CURRENT RIPPLE REMOVING CIRCUIT CONTROLLER

ULD5121, ADAPTIVE 100/120Hz CURRENT RIPPLE REMOVING CIRCUIT CONTROLLER

UTC ULD5121 is a controller, which drives external NMOSFET to remove the 100/120Hz LED current ripple on AC/DC power by a capacitor between VC and GND.

The chip ensures minimum power dissipation on NMOSFET while removing LED current ripple relying on the adaptive technology.
