LMC2626
CMOS LDOR Buffer Chip for Row
Inversion Flat Panel Display Systems
General Description
The LMC2626 integrated circuit is specifically developed for
a row inversion TFT FPD system architecture It is designed
only to be used in conjunction with National’s LM2625
switching regulator chip
Built on National’s advanced CMOS CS80 process this chip
generates a high-power precision square-wave from a digi-
tal sync signal The chip also contains thermal shutdown
circuitry system shutdown circuitry and a low drop-out volt-
age regulator to generate a 4 2 volt supply from an external-
ly applied reference voltage of 1 227V
