3 Description
The TPS65631W is designed to drive AMOLED (Active Matrix Organic Light Emitting Diode) displays requiring positive and negative supply rails. The device integrates a boost converter for VPOS and an inverting buck boost converter for VNEG and is suitable for battery-operated products. The digital control pin (CTRL) allows programming the negative output voltage in digital steps. The TPS65631W uses a novel technology enabling excellent line transient performance.
