Additional Details

The OZ961ISN-A-O-TR utilizes a pulse-width modulation (PWM) control scheme to regulate the current flowing through the CCFLs. This allows for precise control of the backlight brightness. It supports both analog and digital dimming control methods, providing flexibility in system design. The IC is designed to operate over a wide input voltage range, making it suitable for a variety of applications. The built-in soft-start function gradually increases the backlight brightness during startup, minimizing stress on the CCFLs and other components. The adaptive dead-time control optimizes efficiency by minimizing switching losses. The frequency synchronization feature prevents beat frequencies that can interfere with other system components, such as audio circuits. The OZ961ISN-A-O-TR is available in a small package, making it suitable for space-constrained applications. The part number includes tape and reel packaging for automated assembly. This device is RoHS compliant.
