OZ965R - High-Efficiency Inverter Controller

Description

The OZ965 is a single chip, high-efficiency, Cold Cathode Fluorescent Lamp (CCFL) backlight inverter controller whose primary function is to convert +5 volt DC power to approximately 600 VAC.

Figure 1.

Features

  • Single-stage power conversion, requiring only a +5 V voltage source Reduces the number of components and board size by 30% compared with conventional design Supports both floating and grounded secondary designs 90% efficiency vs. typical 75% efficiency of conventional designs Internal open-lamp and short-circuit protections Wide dimming range Supports multiple CCFLs Simple and reliable 2-winding t.
