Working Principle
The MMPF0100F1EPR2 operates by converting a higher input voltage to a lower and more stable output voltage. It uses a high-efficiency, high-frequency, non-isolated DC-DC switching regulator to generate the output voltages. The voltage regulator is based on a pulse width modulation (PWM) control type. The input voltage is first compressed by an internal step-down switch, and then the output voltage is regulated by the PWM controller and the output current is limited by a current setting controller. The MMPF0100F1EPR2 also has overvoltage protection, overcurrent protection, over temperature protection and soft start features to ensure safe and reliable operation.
