MP2565DN-LF-Z Application Field and Working Principle

PMIC (Power Management IC) voltage regulators, namely DC DC Switching Regulators, are used in a variety of products and applications to provide an optimum power solution for the device. One such voltage regulator product is the MP2565DN-LF-Z DC DC switching regulator, designed and manufactured by Monolithic Power Systems (MPS).

Application

The MP2565DN-LF-Z is used in consumer, industrial and automotive applications; as it is capable of providing a highly efficient and reliable power solution. This DC DC switching regulator is used for output power (Po) up to 25W, input voltage (Vin) range from 4.75V-40V and output voltage (Vout) between 0.6V-18V. It supports a wide input voltage range and is specifically designed to support wide temperature range applications with an operating range of -40°C to +125°C.

Working Principle

The MP2565DN-LF-Z works on the principle of a hysteretic controller that regulates the current through an inductor. The device is a non-synchronous low profile DC DC switching voltage regulator that uses a low-side MOSFET switch with a synchronous rectified top-side MOSFET switch. The switching frequency of the device is fixed at 400kHz and is internally set.

The device also incorporates an Analog Error Amplifier (EA) which is used to control the mode of operation of the regulator. The oscillator frequency is set by an external resistor or two resistor divider network, which can be used to optimize the efficiency as well as minimize the overall system cost.

The device also has an integrated over-voltage protection circuit for output over-voltage protection. This over-voltage protection circuit limits output voltage to the desired value when the output voltage exceeds the over-voltage threshold. Other features of the device include adjustable soft-start, adjustable current limiter, skip-mode control and power-good indicator.

Conclusion

The MP2565DN-LF-Z is a high power, non-synchronous, low voltage, DC DC switching regulator and is capable of providing a tightly regulated output voltage with very low noise and ripple characteristics. The device has a wide operating range, with precise output voitage settings and temperature and current protection features, making it an ideal choice for many applications.
