The MP2313GJ-P is a DC-DC switching regulator employed in power management applications. It falls within the Voltage Regulators family of products and is specifically designed as a point-of-load converter. A point-of-load converter is used to efficiently step down a higher voltage to a lower one so that it can be used to power microprocessors, memories and other integrated circuits. It is designed with improved power efficiency and a high accuracy level making it an ideal choice for power system applications.

The MP2313GJ-P device is based on a buck (step-down) topology and uses pulse-width-modulation (PWM) to deliver a steady output voltage despite changing loads. It employs a fixed frequency control PWM with a wide range of input voltage from 2.7V to 17V. The device supports output voltage settings as low as 0.6V to 6V and can operate with a power efficiency up to 96%. Its integrated feedback loop ensures stable regulation and small output voltage ripple. It also comes with a typical hot-swap circuit for inrush current limitation, which helps to prevent a high current peak when the regulator is turned on.

The MP2313GJ-P has an input range of 2.7V to 17V and can support up to 2A of steady load current while providing a low output drift rate of 0.02%. It also has short circuit protection, over-temperature protection, and under-voltage lockout (UVLO) protection, which ensures that the output voltage is maintained at its setpoint despite dynamic load changes. With its wide input voltage range and flexible output voltage options, the MP2313GJ-P is a reliable choice for powering a range of electrical components.

The working principle of the MP2313GJ-P includes an input during the on-time of the device, which allows current to enter the inductor. As the inductor’s energy builds up, the switch transitions to an off-time and the energy stored in the inductor is then transferred to the output capacitor, which smoothens the output voltage and maintains the stability of the output voltage. The internal feedback loop senses any changes in the output voltage and the controller adjusts the on-time and off-time accordingly, to keep the output voltage constant.

The MP2313GJ-P is particularly well suited as a buffer to stabilize the output voltage of many microprocessors, memories, ASICs and SoC devices. Its high cost efficiency, high power efficiency and low noise, make it a perfect choice for any system-level applications, especially in point-of-load management designs. It is also used in Enterprise and Comms applications, including embedded systems, data acquisition, and industrial control.

The MP2313GJ-P is a highly efficient and low noise, DC-DC switching regulator. With a wide input voltage range supported and a range of output voltage settings, it is ideal for managing the power of a range of integrated circuits. High power efficiency and a low output drift rate make it an efficient solution for point-of-load designs, while its protections ensure robust operation and reliable power delivery.
