Additional Details

The OZ964ISN-C-0 employs Pulse-Width Modulation (PWM) dimming to accurately control the lamp's brightness, allowing for a wide dimming range. Its integrated protection features safeguard the CCFL and the controller itself from potential damage caused by overvoltage, overcurrent, or short circuits. The soft-start functionality reduces stress on the lamp during start-up, thus extending its operational life. Burst mode operation further enhances power efficiency, especially at lower brightness levels. The OZ964 series is well-regarded for its robust performance and comprehensive protection capabilities, making it a popular choice for LCD backlighting applications. External components, such as a MOSFET and a transformer, are required to complete the CCFL driver circuit. The part number suffix likely indicates specific packaging details. Consult the datasheet for detailed electrical characteristics and application circuit examples. Precise lamp current and voltage regulation ensure consistent brightness and color across the display.
