Description
The OZ978G is a high-efficiency, Cold Cathode Fluorescent Lamp (CCFL) backlight inverter controller. It converts +5 volt DC power to approximately 600 VAC and performs the lamp dimming function with an analog voltage or low frequency Pulse Width Modulation (PWM) control. The OZ978G utilizes the low energy loss resonate mode principle to deliver a very high efficiency inverter, driving the transformer primary with a variable pulse width voltage directly from the +5v supply.
Specifications and 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 transformer design
- Eliminates leakage current when used in a floating secondary design
- Constant-frequency design eliminates interference with LCDs
Application Scenarios
The OZ978G can be used in various applications where a high-efficiency inverter for CCFL backlighting is required. It is suitable for use in LCD displays, monitors, televisions, and other electronic devices that utilize CCFL technology.
