Power Supply
The STV7619 is designed to drive panels up to 42” with low voltage logic supplies (pins VCC and
VDD). In this case, pin VDD must be connected to pin VCC. The driving of large panels (50”, 60”)
requires a 100 nF capacitor connected between pin VDD and the ground. An internal charge pump
provides a higher driving voltage for the low stage. If requested, higher performances are obtained
when a 12V power supply is directly connected to pin VDD.
The logic supply management of the output stage mainly depends on the write current value of the
plasma cells. The write current is related to the size of the PDP. The following figures illustrate the
different possibilities to supply the STV7619 according to the current drive performances requested
by the plasma panel.
