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 V_IOand V_COREbuck converters are for the T-CON.

The V_AVDDboost converter and V_HAVDDbuck 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.

5-bit Sync. Buck Converter V_CORE: 0.8V…3.3V

♦2MHz Switching Frequency

♦2.5A Switching Current Limit

6-bit Sync. Buck Converter V_HAVDD: 4.8V…11.1V

♦750kHz Switching Frequency

♦1.7A Switching Current Limit

4-bit Charge Pump Controller VGH: 20V…35V

♦4-bit temp. Compensation Offset: 0V … 15V

4-bit Charge Pump Contr. VGL: -5.5V…-14.5V

2-bit Gate Pulse Modulation (GPM): 0V…15V

Thermal Shutdown

Also, a high voltage stress (HVS) mode for the V_AVDD

and a V_AVDDisolation switch is integrated.

G5567 offers high current capabilities, and is ideal for

large screen LCD monitors panels and TV applications

with 12V supply voltage.
