7. LCD Power Supply

The built-in LCD power supply is equipped with input voltage regulator, voltage charge pump and bias

voltage generating circuit with active buffer instead of passive resistor voltage dividing network. The

input voltage is regulated to LVL2 using the internally generated reference voltage. LVL2 can be adjusted

by resistor between LCDGS and LVL2.

LVL2 adjustment guideline: First, the level of VDD must be 0.3 volt higher than LVL2 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 LVL2 can only be set at 1.9 volts max.
