SLVS760A–APRIL 2007–REVISED MAY 2007

Compact LCD Bias Supply for TFT-LCD TV Panels

FEATURES

APPLICATIONS

•

LCD TV Panel

•

6 V to 14 V Input Voltage Range

•

LCD Monitor

Vs Output Voltage Range up to 19 V

Boost Converter With 3.5-A Switch Current

Boost Converter Overvoltage Protection

DESCRIPTION

The TPS65167 offers a compact power supply

solution to provide all voltages required by a LCD

panel for large size monitor and TV panel

applications running from a 12-V supply rail.

2.5-A Step-Down Converter With 3.3-V Fixed

or Adjustable Output

•

750 kHz Fixed Switching Frequency

150 mA Negative Charge Pump Driver for VGL

50 mA Positive Charge Pump for VGH

LDO Controller for Logic Supply

Gate Voltage Shaping for VGH

Temperature Sensor Output

The device generates all 3 voltage rails for the TFT

LCD bias (Vs, VGL and VGH). In addition to that it

includes a step-down converter and a LDO controller

to provide two logic voltage rails. The device

incorporates a high voltage switch that can be

controlled by a logic signal from the external timing

controller (TCON). This function allows gate voltage

shaping for VGH. The device also features a high

voltage stress test where the output voltage of VGH

is set to typically 30 V and the output voltage of Vs is

programmable to any higher voltage. The high

voltage stress test is enabled by pulling the HVS pin

high. The device consists of a boost converter to

provide the source voltage Vs operating at a fixed

switching frequency of 750 kHz. A fully integrated

positive charge pump, switching automatically

between doubler and tripler mode provides an

adjustable regulated TFT gate on voltage VGH. A

negative charge pump driver provides adjustable

regulated output voltages VGL. To minimize external

components the charge pumps for VGH and VGL

operate at a fixed switching frequency of 1.5 MHz.

The device includes safety features like overvoltage

protection of the boost converter, short-circuit

protection of VGH and VGL as well as thermal

shutdown.
