TPS65170 Overview
The TPS65170 provides a simple and economic power supply solution for a wide variety of LCD bias applications. In typical display panel applications, the boost converter generates the display panel’s source voltage VS, the buck converter generates the system’s logic supply VLOGIC, and the two charge pump controllers regulate the external charge pumps generating the display transistors’ on and off supplies VGH and...
