The MPQ4430GL-P is a DC/DC switching regulator from four channel Digital Power MOSFET. It is designed to provide a reliable, efficient and low-noise power supply solution when used in DC/DC power conversion. It can be used as a primary or secondary regulator, depending on the application. With its unique patented digital power MOSFET design and power stage, this regulator offers wide input voltage range and high efficiency.

The MPQ4430GL-P features a low startup current and a low ripple and noise performance. It can operate from an input voltage of 2.5V up to 45V and deliver up to 28A of continuous output current. This regulator is well-suited for automotive and industrial applications.

The MPQ4430GL-P has a single-stage buck converter that operates in two different modes: continuous conduction mode (CCM) and discontinuous conduction mode (DCM). In CCM, the switch current can reach up to a certain value and then will be decreased to a lower value until its duty cycle reaches 50%. In DCM, the switch current will be at a lower value until it is no longer needed and the duty cycle reaches 0%. This feature makes the MPQ4430GL-P suitable for use in a variety of applications. It can also be used in flyback converters, reverse-polarity protection, and wide input voltage range applications.

The MPQ4430GL-P has built in protection features such as over current protection, over temperature protection, over voltage protection and under voltage protection. It also has built in under voltage lockout (UVLO) and a cycle-by-cycle current limitation. The device also comes with a built-in interleaved delay for push-pull operation, which helps reduce output EMI emissions. Additionally, the device features a high frequency PWM pulse train, and the switching frequency can be adjusted from 400 KHz up to 3.2 MHz.

Finally, the MPQ4430GL-P comes with a wide range of features, making it a great choice for many DC/DC switching regulator applications. Its single stage-buck converter operation allows for a high efficiency as well as low output noise. Its protection features help keep the system safe, while the adjustable switching frequency adds flexibility and can help reduce EMI emissions. Its input and output filtering capabilities also make it an excellent choice for a wide range of applications. When all the advantages of the MPQ4430GL-P are taken into account, it is clear to see why it is such a popular choice for DC/DC switching regulator applications.
