OZ964

      OZ964 is designed for both DC/DC and DC/AC high-voltage applications.It is a high efficiency, Pulse Width Modulation (PWM) controller.The average current mode control is used to DC/DC converters where both voltage and current feedback are required,it also is used to Cold Cathode Fluorescent Lamp (CCFL)_ backlight applications for small and large Liquid Crystal Displays (LCD). In addition, OZ964 reaches to a high power-conversion efficiency which results 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.
There are 12 features of OZ964.The first is that it has Controller for high-voltage DC/DC and DC/AC converters. The second is that it has High efficiency, zero-voltage switching.The third is that it hasSupports wide input voltage range.The forth is that it hasConstant operating frequency.The fifth is that it has Built-in PWM dimming control with wide dimming range.The sixth is that it hasSoft start functionThe senventh is that it hasBuilt-in intelligence for ignition and normal operation of CCFLs.The eighth is that it has Built-in open-lamp protection and overvoltage protection.The ninth is that it has Shutdown delay for input voltage brownout condition.The tenth is that it is Built-in under-voltage lockout protection.The elenveth  is that it has Toggle pin to reset the IC after shutdown.The twelveth is that it has Low stand-by power.If the input voltage suddenly drops and subsequently resumes to a normal level,OZ964 also provides a shutdown delay function that will keep the inverter module in normal operation for a short period of time . The shutdown delay time is user-defined.OZ964 operates with a standby current of approximately 200uA.
      The VDDA is 7.0V and the GNDA is PGND +/- 0.3V.Signal inputs are -0.3V to (VDDA +0.3)V .Operating Tempereture of OZ964 is from 0 to 70  and OZ964I is from -40  to +85 .Operating junction temp.is 125 .Storage temp. is from -55   to 150
