S1F75520 Series

Charge-pump DC/DC Converter &

Voltage Regulator with V^COM

ꢀ DESCRIPTION

The S1F75520 is a TFT liquid crystal panel power supply IC. A single power input generates the bias voltage

necessary for driving the liquid crystal. The voltage conversion circuit does not need any external transistors or

diodes, and since all internal CMOS transistors are configured from a charging pump type DC/DC converter, it

is most appropriate for lowering the power consumption of the LCD module.

Combining the S1D19200 or other source drivers and the S1D17917 or other gate drivers may further lower the

LCD module power consumption.

ꢀ FEATURES

• Power supply voltage··········· 2.7 to 3.6V single power input

• Self current consumption ····· Typ. 160 µA

• Standby current ··················· 5 µA

• Built-in charging pump type DC/DC converter voltage conversion circuit

• Outputs positive power supply voltage VSCE for the source driver

· Outputs from the primary booster circuit and the source driver voltage regulator.

· VSCE output voltage can be set within 3.5V to 5.0V from external resistors.

• Outputs positive power supply voltage VGON for the gate driver.

· Outputs from the gate driver voltage regulator and the secondary booster circuit.

· Output voltage can be set within 6.6V to 20V from an external resistor.

• Outputs negative power supply voltage VGOFF for gate driver.

· Outputs from the gate driver voltage regulator and the tertiary booster circuit.

· Output voltage can be set within –15 to –6.6V from an external resistor.

• Built-in counter-voltage VCOM output voltage

· Outputs to the polarity input pin POL synchronously.

· Central voltage of the output voltage can be set within 0.0 to 2.5V.

· Central voltage of the output voltage can be controlled by the analog input signal (VCENT) or the digital input

signal

· Digital input signal controls are made through a 3-line system (BDATA, BCK, XBCS).

· The output voltage amplitude can be set within 3.0 to 5.5V range.

· The output amplitude is controlled through analog input signal (VSWIN).

· Built-in output off function

• Built-in logic power supply voltage regulator

· The output voltage can be set within 1.5 to 1.8V range.

• Built-in soft start circuit

• Built-in discharge circuit

• Built-in CR oscillator circuit

• Shipping forms ················· TQFP12–48pin (S1F75520F0A0000)
