Part Number: OZ9972A
Function: High Power LCD TV Controller
Package: SOP 24 Pin Type or SSOP 28 Pin Type
OZ9972 / OZ9972A 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.
1. OZ9972:System synchronization for dimming and operation frequency
2. Full-bridge topology
3. Integrated high side N-MOSFET driver
4. High drive capability and soft start function
5. Constant operating frequency
6. Built-in intelligence to manage lamp ignition and normal operation of CCFLs
7. Open-lamp, over-voltage, over-current, and under-voltage lockout protection
8. User-defined striking and shutdown delay timers
9. Soft start function
