    There are two control signals that come form system to control lamp brightness. One signal is 
    named DAC_BRIG, which limits current to meet LCD lamp current specification. Another one is 
    named PWM, which adjusts lamp brightness. This inverter brightness is adjusted by PWM burst 
    mode. The PWM burst mode is that turning on and off the lamp at rate of 150Hz. The effective 
    brightness is a function of the duty cycle.
    Features
    1. Wide range 9V to21V input voltage.
    2. Birghtness adjustment by PWM duty mode.

    3. Automatic brightness compensation for input voltage variation.
    NOTE:  Please pay attention to the fellowing:
    *1. Limited lamp maximum current by DAC_BRIC signal: 
         When DAC_BRIG voltage is 0V and INV_PWM enables (100%), lamp has max. current.
        When DAC_BRIG voltage is 3.3V and INV_PWM enables (100%), lamp has min. current.
        DAC_BRIG signal comes from system chipset with internal resistance of 3K

    *2. Inverter operating frequency should be within specification (51-59kHz) at max. and min. 
    brightness load.
    *3. INV_PWM enable implies INV_PWM signal is High level (On duty cycle is 100%). It it a square 
    wave of 150Hz to adjust backlight brightness that is a function of PWM duty cycle. Backlight 
    brightness is maximum value under INV_PWM at 100% and brightness is minimum under 
    INV_PWM at 40%.
    *4.The system interface signals belong to 3.3V.
    *5. Please make sure open lamp output voltage should be within starting voltage specification.
    *6. Inverter should pass human body safety test.
    *7. Inverter should no smoking by any component open/short test.
    *8. Transformer voltage stress should not be over 85% under any condition.
