TPS65135RTER

The TPS65135 device is a high-efficiency split-rail power supply. The converter utilizes a single-inductor multiple-output (SIMO) topology, minimizing the number of external components required. The device employs a buck-boost topology to generate both positive and negative output voltages that can be above or below the input supply voltage. The SIMO topology delivers excellent line and load regulation — a critical characteristic for applications such as preventing input voltage variations caused by transmission phases in mobile communication systems from interfering with handset displays. The device can also serve as a general-purpose split-rail power supply when the output current mismatch between the two rails is less than 50%.
