BD9141MUV-E2 Application Field and Working Principle BD9141MUV-E2 integrated circuit is a DC-DC switching regulator that is typically used in System-on-Chip (SoC) power circuits to provide multi-output voltages from a single voltage input. The integrated circuit features a low quiescent current, high efficiency and low output noise.OverviewBD9141MUV-E2 is a high-performance DC-DC switching regulator designed for use in power circuits of SoCs or other integrated circuits. It integrates a highly efficient buck-boost switching regulator, a switch-mode synchronous rectifier and a power management IC.The BD9141MUV-E2 is designed to operate within a wide input voltage range, and is capable of providing multi-output voltages. The output voltage ranges can be selected and adjusted in steps of 2.5mV. The device is capable of delivering up to 200mA of continuous current per output.The integrated circuit has a low quiescent current of only 2μA, and a low switching frequency of 300 KHz. The integrated circuit also features high efficiency and low output noise. Furthermore, the device is protected against overvoltage, overcurrent and overtemperature.Working PrincipleThe BD9141MUV-E2 works on the principle of buck-boost switching regulation. The integrated circuit contains a comparator, a power MOSFET, and a feedback and control circuit.When the input voltage is greater than the required output voltage, the power MOSFET is operated in buck mode, reducing the voltage across its terminals. When the input voltage is lower than the required output voltage, the power MOSFET is operated in boost mode and increases the voltage across its terminals. The feedback and control circuit measures the output voltage and adjusts the switching frequency of the power MOSFET to maintain the required output voltage.Advantages and FeaturesThe main advantages of the BD9141MUV-E2 are its highly efficient switching regulator, its low switching frequency and its low quiescent current. The integrated circuit also features a wide input voltage range, adjustable output voltage in steps of 2.5mV and protection against overvoltage, overcurrent and overtemperature.The integrated circuit is suitable for use in SoC and other integrated circuits where a high efficiency, low noise and wide range of voltage conversion are required. ApplicationsThe BD9141MUV-E2 is typically used in power circuits of SoCs and other integrated circuits. It is suited for applications such as computing, communication, instrumentation, medical equipment and automotive systems.
