Additional Details

The OZ964SN-C-0-TR utilizes Pulse-Width Modulation (PWM) dimming to accurately control the lamp's brightness, offering a wide dimming range for the display. The integrated protection mechanisms safeguard the CCFL and the controller from potential damage caused by overvoltage, overcurrent, or short circuits. The soft-start feature minimizes stress on the lamp during start-up, prolonging its lifespan. Burst mode operation further improves power efficiency at lower brightness levels. External components, such as a MOSFET and transformer, are typically required to complete the CCFL driver circuit. This IC is widely used in various LCD backlighting applications due to its stable performance and comprehensive protection features. The 'TR' suffix indicates that the part is supplied in tape and reel packaging. Consult the device datasheet for detailed electrical characteristics and application circuit examples. Precise lamp current and voltage regulation ensure consistent brightness and color across the display panel.
