Working Principle

The MAX77826EWJ+T works by using an internal PWM controller and an internal voltage regulator. The PWM controller controls the output voltage by using a high and low voltage reference to generate a pulse width modulated signal, and this signal is then used to control a power transistor, allowing the output voltage to be adjusted. The internal voltage regulator then uses a feedback loop to adjust the output voltage to the desired level. Finally, the Active Discharge feature helps keep the output current in check when the device is switched off.
