Additional Details

The OZ964ISN-C-0-TR utilizes Pulse-Width Modulation (PWM) dimming to precisely control the lamp brightness, providing a wide dimming range. The integrated protection features ensure safe and reliable operation by preventing damage from overvoltage, overcurrent, and short circuits. The soft-start function minimizes stress on the CCFL during startup, contributing to a longer lifespan. Burst mode operation allows the controller to operate more efficiently at low brightness levels by reducing switching losses. External components, such as a MOSFET and transformer, are typically used in conjunction with the OZ964ISN-C-0-TR to complete the CCFL driver circuit. This IC is known for its stable performance and is designed to meet the demanding requirements of modern LCD backlighting applications. Consult the datasheet for detailed electrical characteristics and application circuit examples. The precise regulation of lamp current and voltage contributes to consistent brightness and color uniformity across the display panel. The 'TR' suffix indicates tape and reel packaging.
