OZ964AGN datasheet pinout


OZ964, OZ964AGN operates in a zero-voltage switching mode that minimizes electromagnetic
interference (EMI). In addition, OZ964 achieves a high power-conversion efficiency resulting in a lower operating temperature and higher system reliability.

OZ964 supports a wide input voltage range and provides a constant, user-defined, operating
frequency, ensuring that the CCFLs operate at a fixed frequency. This eliminates interference
among CCFLs and the LCD panel. Interference causes electromagnetic compatibility (EMC)
problems and may create visual effects (waterfall) on LCD panels. The controller provides a phase-shift square wave output that is able to drive a full bridge power train. […]
