It can be easily integrated into multiple types of boards and has a minimum package footprint. This particular component was designed to be used in automotive, industrial, and medical applications where high power suppression is needed.

Features

The MP28255EL-LF-Z has a number of features that set it apart from other DC-DC switching regulators. First, it has a high power conversion rate, with an output current rating of up to 2A. Additionally, it has a wide input voltage range of 4.5V to 18V, can operate at voltages as low as 2.5V, and it has a minimum standby current of 0.07mA. Other features include a high efficiency level of up to 87%, an adjustable frequency for operation up to 1.3MHz, and a programmable soft start.

Application

The MP28255EL-LF-Z is especially suited for automotive, industrial, and medical applications that require high power suppression. Common applications include on-board battery charging solutions, beamed power systems, motor control systems, portable medical equipment, security systems, and automotive drive systems.

Working Principle

The MP28255EL-LF-Z is a DC-DC buck converter operating in the switching mode. It regulates the input voltage and current to the output voltage and current. This is done by turning the device on and off, depending on the input voltage. When the input voltage is higher than the output voltage, the device turns on and connects the input to the output nodes, thus allowing for the power conversion. When the input voltage is lower than the output voltage, the device turns off, and the output voltage is maintained.

The MP28255EL-LF-Z features an adjustable pulse-width modulation (PWM) controller to control the switching of the device. This allows for fine-tuning of the output voltage, current, and frequency, depending on the application’s needs. Additionally, an internal circuit is used to protect the device from overvoltage conditions and overheating.

Conclusion

The MP28255EL-LF-Z is a versatile DC-DC switching regulator tailored for high power-suppression applications. It has a number of features that make it suitable for automotive, industrial, and medical applications, such as its wide input voltage range, high efficiency level, programmable soft start, and adjustable frequency. Additionally, its PWM controller and internal protection circuits make it even more reliable and easier to use. This device is an ideal choice for board designers and engineers looking for an efficient DC-DC converter.
