詳細(xì)介紹

  • The AOZ1977-1  is  a high-efficiency LED driver 

    controller for high voltage LED backlighting 

    applications. It is designed to drive high-brightness 

    LED light bar in LED TV applications. The AOZ1977-1 

    can support a wide range of input and output 

    voltages. The input bias voltage of AOZ1977-1  is 

    from 8V to 30V.

    The AOZ1977-1 has multiple features to protect the 

    regulator under fault conditions. A control pin can 

    disable an external switch to disconnect the LEDs 

    current path from the output in PWM dimming or 

    under catastrophic failure conditions. Cycle-by-cycle 

    current protection limits the peak inductor current. 

    Thermal shutdown provides another level of 

    protection.

    Low feedback voltage (500mV) helps reduce power 

    loss.

    The AOZ1977-1 features sync function to allow for 

    synchronization with  external clock or  multiple 

    AOZ1977-1.

    The AOZ1977-1 is available in a standard SO-16

    package and operates over the temperature range of 

    -40°C to +85°
