Working Principles

The TPS2220APWPR operates as a synchronous buck converter, converting a higher input voltage to a lower output voltage. It utilizes pulse width modulation (PWM) to control the switching of the internal power MOSFETs, regulating the output voltage according to the feedback signal.

When enabled, the IC starts by soft-starting the output voltage, gradually ramping it up to the desired level. It continuously monitors the output current and temperature, providing overcurrent and thermal shutdown protection if necessary. The under-voltage lockout feature ensures proper operation within the specified input voltage range.
