Working Principle of XC6120C222HR-G

The XC6120C222HR-G has an input voltage monitoring circuit and a pulse width modulated (PWM) control circuit that regulate the output voltage. The circuit contains a voltage reference, an error amplifier, a voltage detector, and a programmable gain amplifier. The reference voltage is digitized and compared with the reference voltage. The mismatch is amplified and the resulting signal is used as the error voltage.The error voltage then controls the internal PWM comparator which in turn drives the output stage.The output stage can be further configured to produce a step-up, step-down, or buck-boost conversion.The voltage detector is used to detect overvoltage or undervoltage conditions and if need be, reset the system in order to maintain system reliability.
