Chapter 127 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 Keyboard controller NS 87591L RTC ICH3-M Keyboard ItemSpecification Keyboard controller NS 87591L Keyboard vendor & model name Acer proprietary keyboard w/o launch button embeded Total number of keypads 87/88/90 keys with 101/102 key emulation Windows logo key Yes Internal & external keyboard work simultaneously Yes Battery ItemSpecification Vendor & model name Sanyo/Sony Battery Type Li-ion Pack capacity 69.93Wh Cell voltage 3.7V/cell Number of battery cell 9 Package configuration Pin 1,2: BATT+: Battery positive power pin Pin 3: Floating pin (3S3P) Pin 4: B/I: Enable LI-ion battery output, connect to 1k resistor to GND in system.

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.
