Preliminary Product Information
DC-DC Power IC for TFT Panel
Where
N : It is the number of charge-pump stages.
V
DIODE
: diodes’ forward voltage
To find the total power dissipated in the device, the power dissipated by each regulator and
the buffer must be added together :

: the thermal resistance of the package to the board
Θ
BA
: the thermal resistance from the PCB to the surrounding air.
