The Working Principle of MP6401DGT-33AD3-LF-P

MP6401DGT-33AD3-LF-P is based on a step-down linear converter which uses PWM to convert an input voltage to an adjustable output voltage. When an external voltage is applied to the input, the internal PWM module generates a switch-mode waveform which is then used to drive the MOSFETs, controlling the magnitude of the output. The switch-mode waveform is adjusted so that the desired output voltage is maintained. An ideal diode is integrated into the design to improve efficiency, with an internal boost controller that charges an external capacitor when the output voltage is above the reference voltage. The device also features a low quiescent current for improved efficiency and power savings.
