PMIC - Voltage Regulators - DC DC Switching Regulators

The MP2495DS-LF-Z is an advanced, high-efficiency dual synchronous synchronous step-down integrated circuit, offering a power density of up to 40A/60V. The dual synchronous step-down integrated circuit relies on two efficient current loops for output voltage control, and is specifically designed for applications in which high current density, high conversion efficiency and tight voltage regulation are required.

This product provides a wide range of application fields, making it suitable for a variety of applications such as Disk drives, VRMs, CPU core power, GPU power and HPC applications. As such, it is an ideal fit for embedded systems, automotive, and high-performance computing.

The MP2495DS-LF-Z is an ideal solution for systems needing maximum power density and efficiency with tight voltage regulation. The on-die synchronous regulators allow the device to provide fast transient response time. The adjustable current limit provides an effective protection against output overload or short circuit, while the ultra-fast soft-start function allows the device to start up quickly, without inrush current.

The MP2495DS-LF-Z actual working principle is the basic regulation principle of the circuits inside the integrated circuit. In the first part, there is an internal feedback loop which compares the output voltage with a stable reference one. This feedback loop is then used to adjust a series of internal switches (transistors), essentially controlling the current flow from the input power source to the output stage.

Basically, the internal transistors will either be switched ON or OFF which, depending on the load condition, will control the transfer of power from the input to the output stage. When the output voltage is lower than the reference, the switching transistors in the MP2495DS-LF-Z will allow more current to flow into the output so that it can get higher while, when the output is higher than the reference, the opposite will happen, meaning that the current will be reduced so that the output voltage goes down again.

By being able to control the current flow in this way, the voltage can be accurately regulated, allowing the device to maintain a consistent output voltage which is incredibly beneficial in power delivery and power management applications. Additionally, by using an internal feedback loop to compare the output voltage value with a reference, the device is able to keep the load current more stable, improving the overall performance of the system.

Overall, the MP2495DS-LF-Z offers a wide range of application fields and provides excellent power density and efficiency with tight voltage regulation. The on-die synchronous regulators can provide fast transient response time and adjustable current limit, further improving the overall performance of the system. The actual working principle of the device is to use an internal feedback loop to compare the output voltage with a stable reference and adjust the current flow accordingly to accurately regulate the voltage.
