Working Principle

The TPS61202DRCT is a buck switch regulator circuit. The input voltage is converted to a regulated output voltage by switching the input voltage at a frequency determined by the voltage loop. This switching is accomplished by a power MOSFET which is switched on and off by a control IC. The duty cycle of the MOSFET determines the output voltage. When the duty cycle is high, the output voltage is high, and vice versa. The output voltage can be adjusted by changing the duty cycle via the voltage loop. The circuit also includes a soft start circuit to prevent any inrush currents during power-up.
