Additional Details

The OZ964ISN uses Pulse-Width Modulation (PWM) dimming to accurately control the lamp's brightness, offering a wide dimming range. The integrated protection mechanisms safeguard the CCFL and the controller from potential damage caused by overvoltage, overcurrent, or short circuits. The soft-start feature helps minimize stress on the lamp during start-up, prolonging its life. Burst mode operation further improves power efficiency at lower brightness levels. External components such as a MOSFET and transformer are required to complete the CCFL driver circuit. Consult the device datasheet for specific electrical characteristics and application circuit examples. Precise lamp current and voltage regulation is a key feature, ensuring consistent brightness and color across the display panel. The OZ964 series is known for robust performance and comprehensive protection.
