Name  
NC  
Function  
Not internally connected.  
2
VGHM  
VFLK  
Output of GPM circuit. This output directly drives the supply for the gate driver circuits.  
Determines when the TFT LCD is on or off. This is controlled by the timing controller in  
the LCD module.  
3
4
5
VDPM  
VDD  
VDPM pin is the enable signal for the GPM block. Pulling this pin high enables the GPM  
while pulling this pin low disables it. VDPM is used for timing sequence control.  
Reference input for gate pulse modulation (GPM) circuit. The voltage at VDD is used to set  
the lower VGHM voltage.  
6
7
AVIN  
OUT  
Op-Amp analog power input.  
Output of the Op-Amp.  
8
NEG  
POS  
Negative input terminal of the Op-Amp.  
9
Positive input terminal of the Op-Amp.  
10  
AGND  
Analog ground for the step-up regulator, LDO, and Op-Amp. Connect directly to DAP and  
PGND beneath the device.  
11  
12  
ADJ  
LDO output voltage feedback input.  
VOUT  
LDO regulator output.
