LCD Bias Supply With Integrated Level Shifters

Check for Samples :TPS65163

In typical display panel applications, the boost

converter generates the display panel source voltage,

V_S; the buck converter generates the system logic

supply, V_LOGIC; and the two charge pump controllers

regulate the external charge pumps generating the

2.8-A Boost Converter Switch Current Limit

Boost Converter Output Voltages up to 18.5 V

display transistors’ on and off supplies, V_GHand V_GL

Boost and Buck Converter Short-Circuit

Protection

The level shifters transform the logic-level control

signals generated by the display timing controller into

the high-level signals needed by the LCD panel. The

nine level-shifter channels are organized in two

groups, each with its own positive supply voltage

(V_GH). Each channel uses a low-impedance output

stage to achieve fast rise and fall times, even when

driving the capacitive loads present in LCD

applications. Channels 1 to 6 also support gate

voltage shaping.

The TPS65163 also provides a reset circuit that

monitors the buck converter output (V_LOGIC) and

generates a reset signal for the timing controller

during power up and power down.
