Description

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 V LOGIC , and the two charge pump controllers regulate the external charge pumps generating the display transistors’ on and off supplies V GH and V GL.
