7.LCD Power Supply
The built-in LCD power supply is equipped with input voltage regulator, voltage multiplier and bias
voltage generating circuit with active buffer instead of passive resistor voltage dividing network. The
input voltage is regulated to LVREG using the internally generated LVAG as reference voltage. LVREG
can be adjusted by resistor between LGS1 and LVREG.
LVREG adjustment guideline: First, the level of VDD must be 0.3 volt higher than LVREG even at the
end of battery life for the regulator to function properly. For example, if the VDD is expected to drop to
2.2 volts when battery is low, then the level of LVREG can only be set at 1.9 volts max. Secondly, the
higher the level of LVREG, the less multiples it requires to pump LVP to same level. For example, to
