Product Overview
The TPS65133 is a Texas Instruments dual-output ±5 V Power_IC in the Power_Management category. It integrates a positive boost converter for the fixed 5.0 V VPOS rail and an inverting buck-boost converter for the fixed -5.0 V VNEG rail. Both outputs are specified with ±1% accuracy and 250 mA output-current capability, with independent converter operation allowing 100% output-current mismatch between rails.
The recommended input supply range is 2.9 V to 5.0 V, with a 3.7 V nominal condition used for electrical characterization. Typical efficiency is over 90% from a lithium-ion battery input when output currents are 50 mA to 200 mA. Switching-frequency specifications are 1.2 MHz to 2.2 MHz for the boost converter and 1 MHz to 2.4 MHz for the buck-boost converter.
The device uses a 12-pin WSON (DPD) package with a 3.00 mm x 3.00 mm nominal body. Layout-related pin facts identify VPOS, VNEG, and PVIN as pins requiring nearby capacitors. Recommended operation covers -40 °C to 85 °C ambient temperature and -40 °C to 125 °C junction temperature.
