The TPS65130/1 operates with an input voltage range of 2.7 V to 5.5 V and can generate both a positive and
negative output. Both converters work independently of each other. They only share a common clock and a
common voltage reference. Both outputs are seperately controlled by a fixed-frequency, pulse-width-modulated
(PWM) regulator. In general, each converter operates at continuous conduction mode (CCM). At light loads, the
negative converter can enter discontinuous conduction mode (DCM). As the load current decreases, the
converters can enter a power-save mode if enabled. This works independently at both converters. Output
voltages can go up to 15 V at the boost output and down to –15 V at the inverter output.
