MGW304815 Working Principle

MGW304815 operates on a buck converter topology and use a pulse width modulation (PWM) control method. The switching of the MOSFETs is regulated by a 600kHz oscillator that turns on and off at the duty cycle set the output voltage. When the oscillator is at high, MOSFETs are switched off whereas when it is is at low, the MOSFETs switch on. The output voltage is regulated by an internal error amplifier that compare the input voltage to an internal voltage reference. The output voltage is adjusted by the error amplifier adjusting the duty cycle.

MGW304815 also features remote sensing, which allows the output voltage to be adjusted accurately over a large output current range. This is achieved by connecting the remote sense pins to the output side, so the voltage drop across the output inductor is taken into account, and the output voltage can be adjusted accordingly.
