The TPS65137ASDSCR is designed to drive AMOLED displays (Active Matrix Organic Light Emitting Diode) requiring positive and negative voltage supply rails. The device integrates a boost converter with LDO post regulator and an inverting buckboost converter suitable for battery operated products. The digital control pin (CTRL) allows programming the negative output voltage in digital steps. The TPS65137ASDSCR 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.
