LCD Bias Solution with Level Shifters for GOA Panels

Check for Samples: TPS65155

FEATURES

DESCRIPTION

The TPS65155 provides an integrated bias and level

shifter solution for GOA panels.

•

3 V to 6 V Input Voltage Range

Boost Converter With 4 A Switch Current Limit

Boost Converter Output Voltages up to 18 V

Boost Converter Overvoltage Protection

The device integrates a boost converter to generate

the source driver supply voltage (V_AVDD), positive and

negative charge pump controllers to generate gate

driver ON (V_GH) and OFF (V_GL) voltages, and an

6-channel level shifter in a single IC. The positive

charge pump controller supports temperature

compensation to reduce V_GHat high temperatures.

Selectable Switching Frequency (640 kHz or

1.2 MHz)

•

Programmable Boost Converter Soft-Start

Temperature-Compensated Positive Charge

Pump Controller

In addition to the above functions, the TPS65155

generates an additional active-low XAO reset output.

•

Negative Charge Pump Controller

4 + 2 Channels of Level Shifters

XAO Reset Signal

Supply sequencing during power-up can be controlled

by an externally generated enable signal.
