The MIC2075-2FBMM is an advanced power management integrated circuit (PMIC). It belongs to the family of power distribution switches, load drivers, and also serves as a universal power bus converter. The device integrates a dual low-height package, leadfree thermal solution, and a wide array of features that enable energy efficient power conversion with fast transient response and high voltage accuracy. This article will discuss the application field and working principle of the MIC2075-2FBMM.

The MIC2075-2FBMM is designed to help power designers enable energy efficient solutions and robustly manage power distribution across multiple devices. With high efficiency and low power dissipation, it can be used as a universal bus interface to enable clean power conversion by providing suitable voltage levels to individual loads. It is also capable of supporting wide input voltage range, low start-up current, adjustable output voltage, and adjustable output current. Additionally, the MIC2075-2FBMM is capable of providing precise voltage regulation, fast transient response time, and overvoltage protection.

The device can be used in a wide range of applications such as notebooks, tablets, industrial control and instrumentation, and personal electronics. It is especially suited for multiple load applications where the load needs to be dynamically managed with precise load current and precise load voltage levels. Additionally, the MIC2075-2FBMM can be used in low-power applications and hot-swap battery approaches as part of an automated power management system.

The MIC2075-2FBMM is based on a basic two-FET topology, or MOSFET buck converter. It requires only two FETs (p-channel, n-channel) in a voltage-mode control design that eliminates the need for complex error-amplifier circuitry. The device also features an internal circuit to track the output voltage and a voltage loop to modulate FET switching. This approach ensures fast transient response and high accuracy of the output voltage. The device provides a wide range of adjustable output current and output voltages as well as power-save mode.

The MIC2075-2FBMM also provides overvoltage protection, ensuring that voltage spikes do not damage the device and other components. Additionally, it ensures that the output voltage, current, and ripple are all held within desired ranges, thereby protecting downstream components and applications. The device also features surge-current protection and current limiting, which provide added protection to the device and other system components.

The MIC2075-2FBMM is an excellent choice for applications that require fast transient response, precision output voltage and current regulation, and overvoltage protection. With its ability to support wide input-voltage range and low startup-current, it is an ideal solution for multiple load and power-save applications. Additionally, it can be used in hot-swap and battery approaches as part of an automated power management system. All of these features combined make the MIC2075-2FBMM a superior choice for applications that require power and energy efficiency.
