The TPS65632 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, all of which are suitable for battery operated products. The digital control pin (CTRL) allows programming the negative output voltage in digital steps. The TPS65632 uses a novel technology enabling excellent line and load regulation.
