26Chapter 1 NOTE: 1. Li-ion Battery: Connect 1K % ohm resistor to GND in Battery PCB. NOTE: B/I pin: Battery can be Charged/Discharged only while this pin is connected to GND. LCD Inverter Specification 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 to turn on and off the lamp at rate of 150Hz. The effective brightness is varied with the duty cycle.

NOTE:
*1. The display can not happen flicker or shutdown.
*2. Limited lamp maximum current by DAC_BRIC signal:
DAC_BRIG signal comes from system with internal resistance of 3K .
When add 1V DAC, the 100% Lamp current will decrease 0.5mA.
*3. Inverter operating frequency should be within specification (50~70kHz) 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 40%.
*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. Inverter should without acoustic at 10cm distance..
Thermal
All components on inverter board should follow below rules:
1. Component using conditions (component stress) must be within component specification including voltage
rating, current rating, temperature etc.
2. Component temperature should follow below:
