  • PQ1U181M2ZPH Application Field and Working Principle
    • Application Field
      • The PQ1U181M2ZPH series is a voltage regulator module (VRM) designed for use in computers, memory modules, and other applications requiring high current and good power supply quality.
    • Working Principle
      • The PQ1U181M2ZPH series is a switching regulator, which is an electronic switch that is used to regulate the output of a power supply. To regulate the voltage of the output, the switch is connected to an inductor and a capacitor. The inductor helps store the energy sourced from the input power, while the capacitor helps to stabilize the output voltage. The switching regulator works by rapidly switching the connection between the supply voltage and the inductor and consequently the capacitor. As the switch is opened, the current and energy stored in the inductor flows into the capacitor and then the output. The speed at which the switch is opened and closed determines the output voltage and the current that is supplied to the output terminals.
    • Features
      • The PQ1U181M2ZPH VRM has many features that promote power efficiency, such as an integrated loop compensator, as well as the ability to adjust the output voltage in increments of 0.01V. In addition, the VRM also has an overvoltage, undervoltage, over temperature and overcurrent protection, making it a reliable source of power for a variety of applications.
