Working Principle of the TPS62740DSSR

The TPS62740DSSR uses a bidirectional buck-boost DC/DC converter to regulate the input and output voltages. The input voltage is applied to the inductor which stores the energy while the switch is closed. This energy is then discharged to the output capacitor when the switch opens. The output voltage is thus regulated to the desired value by the control circuit.

The control circuit monitors the output voltage and adjusts the inductor duty cycle to maintain a constant output voltage. The duty cycle controls the amount of energy stored in the inductor and hence the output voltage. The TSP62740DSSR also has a synchronous control circuit which enables the use of synchronous rectification for improved efficiency and a PWM control which enables the use of a single super-capacitor.
