MP28119EG-LF-Z is an integrated Circuit (IC) Device belonging to the DC-DC Switching Regulators family that is part of the larger Power Management Integrated Circuit (PMIC) product category. This device is a buck regulator circuit specifically designed to convert a voltage provided by an external power source such as a battery, a USB port, or a DC/DC converter, to a different lower positive or negative output voltage.

Application Field:

The primary application field of the MP28119EG-LF-Z is electronics design and development, particularly in the mobile device, computing and telecommunications equipment industry. Its small size makes it suitable for devices such as smart phones, digital cameras, digital camcorders, laptop computers and tablet PCs, for which it is capable of providing a regulated output voltage for powering displays, processors, user interface, audio and image processing units, memory, and other electronic components.

Working Principle:

The working principle of the MP28119EG-LF-Z is based on the Buck Converter topology, which is a type of DC-DC voltage regulator that is widely used for its relatively high efficiency, small size and simple implementation. Basically, the device achieves voltage regulation through the use of a switching element, which eliminates the need for large and expensive inductors.

The device consists of a controller and an internal driver, which form an integrated circuit that controls the switching action of this device. This switching circuit either allows or blocks current flow from the source to the load. The timing of the switching action is controlled by varying the frequency of an oscillator, that can be set by the user of the device.

The efficiency of the device is achieved through the use of Pulse Width Modulation (PWM) control, which is a variation of the Duty Cycle technique. The output voltage of the device is proportional to the duty cycle of the pulse pulsewidth PWM signal applied to the controller of the device. The circuit provides an adjustable voltage up to a certain maximum voltage, typically 25V, depending on the model.

The MP28119EG-LF-Z features built–in protection features to guard against input overvoltage, output overvoltage, over current, and output short circuit. The device also offers high efficiency, up to 95%, high switching frequencies of up to 1 MHz, under voltage lockout, and a built–in over temperature circuit for thermal protection.

In conclusion, the MP28119EG-LF-Z is an integrated DC-DC Switching Regulator device that is optimized for applications such as mobile devices, computing and telecommunications equipment, with the capability of providing a regulated voltage up to 25V, from an external power source such as a battery, a USB port, or a DC/DC converter. Its high efficiency and small size make it a great choice for these types of applications.
