Working Principle of TPS62173DSGR

The working principle of TPS62173DSGR is based on the buck converter topology. In this topology, the device receives power from a DC input voltage source, converts it to a DC output voltage, and then regulates the output voltage to maintain precise voltage control. The device consists of a power switch, an inductor, a capacitor, and control circuitry. The switch is controlled by a pulse width modulation (PWM) circuit.

The switch is turned on or off via the PWM circuit, causing the current flow in the inductor to increase or decrease. This in turn causes the output voltage to increase or decrease accordingly.

The control circuitry monitors the output voltage and adjusts the duty cycle of the PWM circuit accordingly. This adjusts the amount of current flow in the inductor, maintaining the desired output voltage level.

Conclusion

The TPS62173DSGR is a robust DC to DC switching regulator, suitable for a wide range of portable and automotive applications. Its high efficiency and precise voltage control make it well suited for power backup and memory stocks. Its working principle is based on the buck converter topology, in which the output voltage is regulated by varying the amount of current flow in the inductor.
