PMIC - Voltage Regulators - DC DC Switching Regulators

MP2562DQ-LF-P is a switching regulator from NXP that finds application in various fields and operates according to a different working principle. This voltage regulator is a synchronous DC-DC converter which offers a low operating input voltage range. It is capable of providing up to 7A of load current in different output voltages.

Application Field

MP2562DQ-LF-P is widely used in applications where high efficiency is an important factor and where low input voltage is needed. It is usually used in industrial and automotive applications such as battery-powered systems, communications, office equipment, and medical equipment. It can also be used in USB power sources, DC/DC converters, and industrial power supplies.

Working Principle

The MP2562DQ-LF-P switching regulator is based on a cascaded structure that consists of an input regulator, a high-side current-mode MOSFET, a low-side current-mode MOSFET and a low dropout linear regulator (LDO). This regulator has a hysteretic mode with a cycle-by-cycle constant off-time control which enables it to adapt to dynamic changes in load power requirements.The input regulator compensates for input voltage changes and provides an isolated base to drive the two MOSFETs of the converter. The MOSFETs control the voltage delivery to the output by regulating the duty cycle of the cycle-by-cycle constant off-time control. The output is then regulated by the LDO.

Conclusion

In conclusion, the MP2562DQ-LF-P switching regulator is a good option when it comes to industrial and automotive applications. It offers high efficiency, low input voltage, and robust operation. Furthermore, its cycle-by-cycle constant off-time control technology enables it to handle changes in load power requirements efficiently and reliably.
