General Description
The G5567 DC-DC converter provides six regulated
voltages required by thin-film transistor (TFT) liquid
crystal displays (LCD) panels. All output voltages are
programmable.
The VIO and VCORE buck converters are for the T-CON.
The VAVDD boost converter and VHAVDD buck converters
are for the source driver and Gamma buffer. Charge
pump VGH and VGL are for the gate driver or level
shifter. VGH voltage is with temperature compensation
for the Gate in Panel (GIP) technology.
Also, a high voltage stress (HVS) mode for the VAVDD
and a VAVDD isolation switch is integrated.
G5567 offers high current capabilities, and is ideal for
large screen LCD monitors panels and TV applications
with 12V supply voltage.
