17. LCD Power Supply Circuit
The LCD power supply circuit generates the LCD voltage needed for display output, which is controlled by pins FNC1
,FNC2 and LCD power supply circuit ON/OFF command. It consists of:
1. Doubler/tripler DC-DC voltage converter.
2. Voltage regulator and LCD voltage command fine adjustment circuit.
3. LCD bias resistor and voltage follower

FNC1 and FNC2 must connect to VDD or VSS.
Don’t connect the external power supply with the built-in LCD power supply circuit ON, it may lead to a breakdown.
17.1 Doubler/Tripler
It is the 2X, 3X DC-DC voltage converter. Please refer to application notes.
17.2 LCD Voltage Adjustment
There are two methods of adjusting the LCD voltage as follows:
17.2.1 Voltage Regulator
Voltage regulator output V5 is adjusted by externally attached Ra and Rb.
