The TPS65138 is designed to drive AMOLED displays (Active Matrix Organic Light Emitting Diode) requiring positive and negative supply rails. The device integrates boost converter and inverting buck boost converter designed suitable for battery operated products. The digital control pin (CTRL) allows programming the negative output voltage in digital steps. The TPS65138 uses a novel technology enabling excellent line and load regulation. This is required to avoid disturbance of the AMOLED display by the input voltage disturbances occurring during transmit periods in mobile phones.
