OZ961IS - Brand New Micron Technology Inc. IC Chips
-
Description
The OZ961IS is a single chip, high-efficiency, Cold Cathode Fluorescent Lamp(CCFL) backlight inverter controller. The primary function of this controller is to convert +5 volt DC power to approximately 600 VAC. Additionally, the OZ961IS performs the lamp dimming function with an analog voltage or low frequency Pulse Width Modulation (PWM) control. It utilizes the low energy loss resonate mode principle to deliver a very high efficiency inverter. The OZ961IS operates at a single, constant frequency in a PWM mode.
Specifications and features
The OZ961IS operates with a single-stage power conversion, requiring only a +5 V voltage source. It reduces the number of components and board size by 30% compared with conventional design. It supports both floating and grounded secondary designs, has 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, and constant-frequency design eliminates interference with LCDs.
Application Scenarios
The OZ961IS is a Cold Cathode Fluorescent Lamp (CCFL) backlight inverter controller that is used in the manufacturing of various electronic products such as laptops, medical equipment, televisions, and other displays with backlights.
Comparison
Advantages- The OZ961IS is a single chip solution for inverter control and lamp dimming function, which reduces the numbers of components needed and helps in size reduction.
- The OZ961IS has a high efficiency of 90% compared to conventional designs, which provides a longer lifespan to the products it is used in.
