MPM3805GQB-Z Power Supplies - Board Mount

DC-DC converters are electrical components that are designed to convert a direct current voltage source into a different direct current voltage output. The MPM3805GQB-Z is a type of DC-DC converter with different applications and a distinct working principle. Here, we focus on its application field and working principle.

Application Field

The MPM3805GQB-Z converter is a DC-DC voltage converter with a low input voltage range. As a result, it is mainly used to step up a low voltage source, such as the 12V batteries used in vehicles. It is also suitable for input/outputs with a difference of up to 35 V. Furthermore, this converter offers high efficiency, high reliability, and low standby power consumption due to its integration of a power switch.

Working Principle

The working of the MPM3805GQB-Z DC-DC converter is based on the buck-boost converter. This converter consists of an inductive load, a boost capacitor, a high voltage switch, and a low voltage switch. The converter takes an input voltage and converts it to a higher output voltage. The output voltage is determined by the switching frequency, the inductance of the load, and the capacitance of the boost capacitor. When the high voltage switch is closed, the inductor accumulates energy from the input voltage. When the low voltage switch is open, the stored energy in the inductor is released and the boost capacitor is charged. This process continues to repeat itself to generate the required output voltage. In addition, this type of converter can provide both step up and step down output voltage depending on the usage and the requirements.

Conclusion

The MPM3805GQB-Z is a type of DC-DC converter that is commonly used to step up a low input voltage source. It is a buck-boost converter and consists of an inductive load, a boost capacitor, and two switches. Through the inductive-capacitor energy conversion process, the converter can provide step up or step down output voltage. Therefore, this converter makes it possible to step up low voltage sources for many applications.
