Working Principle

The MAX16977RAUE/V+T DC-DC switching regulator works by converting an input voltage of 4.75V to 28V into a regulated output voltage. The regulator uses a pulse width modulation (PWM) control scheme, which is implemented through the use of an internal power switch, a MOSFET gate driver and current sense circuitry. The PWM controller compares the output voltage to a feedback signal, which is derived from an external resistor divider connected to the output terminal. It then adjusts the duty cycle of its internal power switch, which in turn adjusts the output voltage. The output voltage is regulated through the use of a phase-locked loop (PLL) circuit. The PLL maintains a constant relationship between the frequency of clock pulses and the frequency of voltage feedback signals, ensuring stable regulation.
