Working Principle

The MPQ2143DJ-AEC1-LF-P is a synchronous buck regulator based on a DC/DC switching regulator topology. It uses a control loop to regulate the output voltage, which is then fed back to the input voltage. The voltage regulator uses a high-side NMOS (n-channel MOSFET) to regulate the output voltage. The NMOS is used to switch the current flow to the load when the feedback voltage from the load exceeds the reference voltage, which is set by the input voltage. When the input voltage is lower than the reference voltage, the current flow is mode from the load to the input, which reduces the output voltage. The output voltage can also be adjusted manually by using the 8-bit DAC-based adjustable load line output. Additionally, the integrated low RDS MOSFET provides for improved power conversion efficiency and better thermal performance.
