Part Number: OZ9972ASN
Function: High Power LCD TV Controller
Package: SOP 24 Pin Type
OZ9972, OZ9972ASN are high performance, Pulse Width Modulation (PWM) controllers designed for large-size LCD TV applications requiring multiple lamps. They achieve high efficiency power conversion with minimal switching loss in a PWM, full-bridge, N-Channel MOSFET topology.
0Z9972, 0Z9972A provide high drive capability, support a wide input range, and provide a constant, user-defined operating frequency.
• OZ9972 : System synchronization for dimming and operation frequency
• Full-bridge topology
• Integrated high side N-MOSFET driver
• High drive capability and soft start function
• Constant operating frequency
• Built-in intelligence to manage lamp ignition and normal operation of CCFLs
• Open-lamp, over-voltage, over-current, and under-voltage lockout protection
• User-defined striking and shutdown delay timers
• Soft start function
