DC DC Converters: MPM3810GQB-33-Z Application Field and Working Principle

DC DC converters are upconverters or downconverters widely used in a variety of industries, and the MPM3810GQB-33-Z is no exception. This product is a high-efficiency, isolated DC/DC converter produced by Murata Power Solutions. It is designed to provide an isolated 3.3V output from a 4.75V to 5.5V input. It is ideal for applications such as wireless base stations, industrial automation systems, control systems, and communications.

Application Area

The MPM3810GQB-33-Z is designed for a wide variety of applications due to its small footprint and its ability to transfer power without expelling heat. It is commonly used in base stations, industrial automation systems, controller systems, and communications systems. In addition, this device can be used for general power sourcing purposes and as a power feed or power regulator.

Technical Features

The MPM3810GQB-33-Z features a 3A output current, a 200kHz switching frequency, and an input voltage of 4.75 to 5.5 volts. It is designed with a high power efficiency of up to 95.6% and is able to provide a stable output voltage of 3.3 volts. The device also offers low ripple, low noise, and a wide temperature range (-40C to 85C).

Working Principle

DC to DC converters convert a direct current (DC) input voltage to a different, regulated DC output voltage. The MPM3810GQB-33-Z works in a buck converter configuration, which means that the device will step down the input voltage and convert it to a lower voltage output. This is done by switching a high-side and low-side switch, and by altering the duty cycle, the output voltage can be regulated. When the duty cycle of the high-side switch is high, the peak output voltage is high, and when the duty cycle is low, the peak output voltage is lower.

Conclusion

The MPM3810GQB-33-Z is a high-efficiency, isolated DC/DC converter that is ideally suited for a range of applications requiring a 3.3V output from a 4.75V to 5.5V input. It features a high power efficiency, low ripple, low noise, and a wide temperature range. It utilizes a buck converter configuration to step-down the input voltage to a regulated output voltage, with the peak output voltage altered by changing the duty cycle of the high-side switch. Due to its efficiency and small footprint, the MPM3810GQB-33-Z is a widely used DC/DC converter for many industrial and consumer applications.
