DESCRIPTIONThe TPS65138is designedto 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 voltagein digital steps. The TPS65138 usesa novel technology enabling excellent line and load
regulation. Thisis requiredto avoid disturbanceof the AMOLED display by the input voltage disturbances
occurring during transmit periodsin mobile phones.
