The TPS65632A is designed to drive AMOLED displays (Active Matrix Organic Light Emitting Diode) requiring three supply rails, VPOS, VNEG and AVDD. The device integrates a boost converter for VPOS, an inverting buck boost converter for VNEG and a boost converter for AVDD which are suitable for battery operated products. The digital control pin (CTRL) allows programming the negative output voltage in digital steps. The TPS65632A uses a novel technology enabling excellent line and load regulation.
