PMIC (Power Management ICs) are integrated circuits that help manage, control, and improve all the power functions of an electronic system. Voltage regulators are a form of PMICs that stabilize the power supply in an electronic system by taking input from either an AC or DC source and adjusting the voltage as needed. There are two types of voltage regulators: linear regulators and switching regulators. The MP28258DD-LF-P is a DC DC switching regulator.

A switching regulator includes an oscillator and power switches that control power to the output terminals. The frequency of the oscillator is controlled by the switching regulator and, along with the amount of time the switches remain open and closed, determines the level of power delivered to the output terminals. MP28258DD-LF-P is a fixed frequency, non-synchronous, step-down DC DC switching regulator that is designed to convert a higher DC input voltage to a lower DC output voltage.

MP28258DD-LF-P employs a buck (step-down) topology, with a wide 4 V to 38 V input voltage range, and is capable of providing up to 3.3 A of continuous output current and up to 6 A of peak output current. The device also has built-in loop compensation, adjustable output voltage, fixed switching frequency (434 kHz), soft-start, and over-temperature protection.

The most important application of the MP28258DD-LF-P is in portable and mobile devices. Portable and mobile devices such as laptop computers, cell phones, tablets, and wearable devices require efficient power delivery in small physical spaces. The MP28258DD-LF-P fits their needs as it provides up to 3.3 A of continuous output current in a 4 mm × 4 mm MLPQ-22 package which is ideal for space-constrained applications.

In addition to being used in small, space-constrained applications, the MP28258DD-LF-P also has applications in a wide variety of consumer, industrial and automotive devices. Its wide input voltage range and its ability to provide up to 3.3 A of continuous output current make it an ideal candidate for powering regulated circuits in consumer and industrial applications. In addition, its adjustable output voltage capability and its ability to deliver up to 3.3 A of continuous output current make it suitable for use in automotive applications where varying input voltages and higher output currents are present.

The MP28258DD-LF-P features constant-frequency, non-synchronous operation, which eliminates the need for loop compensation, and its wide output voltage range allows it to generate any regulated output voltage from 0.8 V to 12 V. It also includes a soft-start function and over-temperature protection, making it a safe and reliable power supply.

The MP28258DD-LF-P combines the advantages of a low-cost buck (step-down) topology with constant-frequency non-synchronous operation, adjustable output voltage capabilities, and a wide input voltage range. This combination of features makes the MP28258DD-LF-P a perfect choice for applications where high-efficiency power delivery is needed in a small, space-constrained package.
