2-A Internal MOSFET Switch
The TPS65150 offers a very compact and small
Main Output Vs up to 15 V With <1% Output
power supply solution that provides all three voltages
Voltage Accuracy
required by thin film transistor (TFT) LCD displays.
Virtual Synchronous Converter Technology
With an input voltage range of 1.8 V to 6.0 V the
device is ideal for notebooks powered by a 2.5-V or
Negative Regulated Charge Pump Driver VGL
3.3-V input rail or monitor applications with a 5-V
Positive Regulated Charge Pump Driver VGH
input voltage rail. Additionally the TPS65150 provides
Adjustable Power On Sequencing
an integrated high current buffer to provide the
VCOM voltage for the TFT backplane.
Adjustable Fault Detection Timing
Gate Drive Signal for external isolation
Two regulated adjustable charge pump driver provide
MOSFET
the positive VGH and negative VGL bias voltages for
the TFT. The device incorporates adjustable power
