Chapter 125 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 to 21V input voltage. 2. Birghtness adjustment by PWM duty mode. 3. Close loop controls lamp current. LCD Inverter Specification This inverter is designed to light up the CCFL of LCD for TravelMate 430 series notebook. It should be supported the following LCD panels.

NOTE:
*1. The inverter can work in 7.5V input voltage (continuous), but 7.5V electronic characteristic will
not be care.
*2. 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.
When add 1V DAC, the 100% Lamp current will decrease 0.5mA.
DAC_BRIG signal comes from system chipset with internal resistance of 3K
*3. Inverter operating frequency should be within specification (45~65kHz) at max. and min.
brightness load.
*4. INV_PWM enable implies INV_PWM signal is High level (On duty cycle is 100%). It is 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 30%.
*5.The system interface signals belong to 3.3V.
*6. Please make sure open lamp output voltage should be within starting voltage specification.
*7. Inverter should pass human body safety test.
*8. Inverter should be no smoking by any component open/short test.
*9. Transformer voltage stress should not be over 85% under any condition.
(turn on overshoot transient and line transient.)
*10. Audio noise should be less than 36dB at 10cm distance.
