General Description
The G5562A DC-DC converter provides regulated volt-
ages required by thin-film transistor (TFT) liquid crystal
displays (LCD) panels in TQFN package. One step-up
converter, one step-down converter, and two charge
pumps convert the 8V to 14V input voltage into four
output voltages. These features complete the power-
supply requirements of large screen LCD panels. The
step-up converter provides source voltages VS and the
step-down converter provides logic voltage for the sys-
tem. The dual charge pumps independently generate
adjustable regulated output voltages VGL and VGH to
bias the LCD. These four blocks operate with a fixed
switching frequency of 500kHz or 750kHz.
Both step-up and step-down converters operate in
asynchronous switch mode. Current mode control pro-
vides fast transient response and eases loop stabiliza-
tion. Fault protection includes cycle-by-cycle current
limit, thermal shutdown, and output-fault shutdown.
Current mode control is used for both charge pumps to
regulate its output voltage, which minimizes output
ripple and capacitor sizes. High voltage switch is used
for gate voltage shaping to improve TFT-LCD display
quality.
The G5562A includes one high-speed high-current
operational amplifier and one high-accuracy LDO for
Gamma buffer reference.
The G5562A is available in a 48-pin TQFN package.
