Beschreibung

The OZ8023 is a voltage-mode, quasi-resonant converter controller, suitable for offline, AC/DC flyback converter applications. It can be used as a single-stage power factor correction controller for an isolated power supply or LED driver applications.

The OZ8025 is a controller for an isolated LED driver application. It provides a proprietary 3-level dimming control to LEDs using an ON/OFF wall switch.
