TPS65124RGTT Description

The TPS65124RGTT DC-DC converter supplies all three voltages required by amorphous-silicon (a-Si) and low-temperature poly-silicon (LTPS) TFT-LCD displays. 

This control architecture operates at a pseudo-fixed frequency to provide a fast response to line and load transients while maintaining a relatively constant switching frequency and high efficiency over a wide range of input and output voltages.
