The working principle of the TPS70912DBVT is based on the well-known B-L-C circuit topology. It consists of an input voltage, a current source and an output voltage. The input voltage is applied to the base-emitter junction of an NPN transistor, while the current source is applied to the collector-emitter junction. The output voltage is taken across the emitter-collector junction and is regulated by controlling the current source. The output current is regulated by controlling the base voltage of the NPN transistor.
