MP38900DL-LF-P Application Field and Working Principle

The MP38900DL-LF-P is a member of DC-DC synchronous buck switching regulator family. It is an efficient, high power, high current density and operationally stable regulator used in a variety of applications.

Application Fields

The MP38900DL-LF-P is most commonly used in the fields of communications, infrastructure, computer peripherals and other applications where low voltage power is required. It can be used for high-current applications as well as for low-power applications.In communications it is ideal for powering Wi-Fi routers and transceivers as well as LTE base station transponders and transceivers. In infrastructure it is useful for powering solid state lamps, sensors and points of sale machines. In computer peripherals it is ideal for powering printer control boards, PC motherboards and power supplies.

Working Principle

The MP38900DL-LF-P works on a principle called Synchronous Buck Switching. This means that the regulator is able to switch rapidly between two different set voltages, depending on its input voltage.At high input voltage, the regulator is able to switch to a higher output voltage. This higher voltage is used to power loads which require a certain amount of power. At lower input voltages, the regulator switches to a lower output voltage. This lower voltage is used to power loads which require less power.In order to achieve this, the regulator employs two major components. These are an inductor, which stores energy and then releases it in a controlled fashion, and a switch, which allows for the output voltage to be varied according to the input voltage.The MP38900DL-LF-P is also equipped with additional protection features, such as under voltage protection, current limit protection, over temperature protection and short circuit protection.

Conclusion

The MP38900DL-LF-P is an efficient, high power, high current density and operationally stable regulator used in a variety of applications. It is often used in communications, infrastructure, computer peripherals and other applications where low voltage power is required. It employs the synchronous buck switching regulator principle to be able switch rapidly between two different set voltages, depending on its input voltage. It is also equipped with additional protection features to ensure safe operation.
