Qualified for Automotive Applications
2.7-V to 5.8-V Input Voltage Range
The TPS65100 offers a compact and small power
supply solution that provides all three voltages
1.6-MHz Fixed Switching Frequency
required by thin-film transistor (TFT) LCD displays.
Three Independently Adjustable Outputs
The auxiliary linear regulator controller can be used
Main Output of up to 15 V With < 1% Output
to generate a 3.3-V logic power rail for systems
Voltage Accuracy
powered by a 5-V supply rail only.
Virtual Synchronous Converter Technology
The main output, VO1, is a 1.6-MHz fixed-frequency
PWM boost converter providing the source-drive

Thermal Shutdown
Available in TSSOP-24 PowerPAD Package
The TPS65100 has an integrated VCOM buffer to
power the LCD backplane. For LCD panels powered
by 5 V only, the TPS65100 has a linear regulator
controller using an external transistor to provide a
