MIC2182-5.0BM-TR is a type of DC/DC switching voltage regulator, primarily used to power mixed-signal, low-power designs in applications such as industrial, computing, consumer and communications industries. This device primarily functions as an integrated low RDS(ON) synchronous buck converter controller for space-limited designs, and is capable of delivering up to 5A of output current.

The MIC2182-5.0BM-TR has built-in fixed frequency, current mode control. Additionally, its voltage output is adjustable through an external resistor divider and is designed to regulate current in a range from 0.45V to 5.5V. The device operates from the input voltage range of 6.9V to 32V.

The main features of the MIC2182-5.0BM-TR include its ultra-wide 8-32V input voltage range, its very low 600mV feedback voltage accuracy, its high-speed output voltage regulation, and its precise overcurrent regulation. The device also contains a slew rate control that enables precise load regulation. This device is also equipped with several internal protection features, such as overvoltage protection, current limit and soft-start.

In addition to its basic function as a DC/DC power controller, the MIC2182-5.0BM-TR also incorporates several other advanced features. These include its external gate drive capability, which enables external MOSFETs to be connected. This feature allows for current regulation of the external MOSFETs, as well as reduced conduction losses. The device also contains an internal synchronous N-channel MOSFET, which helps to improve efficiency and reduce costs.

The MIC2182-5.0BM-TR also features a dynamic voltage scaling (DVS) feature that allows for efficient changing of the output voltage. This device is also designed to operate in either PWM or Pulse Frequency Modulation (PFM) modes, and uses a low-side MOSFET to drive the load. This device also has a hysteretic mode control and programmable switching frequency, enabling designers to optimize power delivery.

The working principle behind the MIC2182-5.0BM-TR is based on synchronous buck controllers. When this device is enabled, an internal voltage is developed across an input capacitor. This voltage is compared against an internal reference, which is then used to determine the duty cycle of the switching transistors. Depending on the output load, the duty cycle will be adjusted to maintain the desired voltage level.

The operation of the MIC2182-5.0BM-TR can be seen as a pulse-width modulation (PWM) system. The device senses the voltage at its input using a voltage divider and compares this voltage to a reference voltage inside the device. When the sensed voltage is higher than the reference, the output switch will stay off, allowing the input voltage to decay until it reaches the reference voltage. Once the voltage has been brought to the reference level, the output switch will turn on and apply power to the load.

In summary, the MIC2182-5.0BM-TR is an integrated synchronous buck voltage regulator designed to provide constant voltage regulation, regardless of the load current. Its features include wide input and output voltage ranges, low-side gate drive capability and adjustable switching frequency, as well as many other features, making it a desirable device for applications requiring precision voltage regulation.
