Additional Details

The OZ964GES utilizes Pulse-Width Modulation (PWM) to precisely control the lamp current, enabling accurate brightness adjustment. 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. The 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 OZ964GES to complete the CCFL driver circuit. The OZ964GES offers stable performance and is designed to meet the demanding requirements of modern LCD backlighting applications. The part number details the packaging type and reel size, so consult the datasheet for specifics. The precise regulation of lamp current and voltage contributes to consistent display brightness and color uniformity.
