The MP6402DN-EF-LF-Z is a step-down regulator IC ideal for always-on applications. It provides up to 3A of output current and greatly improves overall power efficiency through its PMIC – voltage regulator – linear architecture. This device operates over a wide input voltage range from 4.5V to 20V, and provides a constant output voltage adjustable from 0.8V to 23V.

At the heart of the MP6402DN-EF-LF-Z is its field effect transistor (FET) which acts as the main switching element. This FET is driven by an internal Power MOSFET driver block with adjustable peak current limit and programmable gate delay time. This driver circuitry allows the regulator to switch at very high speed, thus improving stability and reducing power losses at the same time.

To further increase power efficiency, the MP6402DN-EF-LF-Z utilizes high efficiency synchronous rectification, as well as programmable adaptive frequency control. The adaptive frequency in this device is designed to make quick adjustments to the switching frequency according to the output current and input voltage. This helps optimize the efficiency without sacrificing stability during heavy loading or wide input voltage.

The MP6402DN-EF-LF-Z also features a slew rate control mechanism. The slew rate control allows the user to choose whether to maximize the load transient response or improve the power efficiency of the entire system by adjusting the slew rate of the output voltage through the external resistor.

Other features of the MP6402DN-EF-LF-Z include a programmable power-saving mode which helps reduce the quiescent current during no-load conditions and improves the overall system efficiency in light load applications. Also integrated into this IC is an internal over-current protection circuit, thermal shutdown protection, over-voltage protection, and under-voltage protection.

The MP6402DN-EF-LF-Z is a highly integrated step-down regulator IC. Its innovative PMIC – voltage regulator – linear design helps improve efficiency while providing robust protection features and excellent transient response. It is perfect for always-on applications where superior power efficiency is a must.
