The MIC2183BM is a member of the line of 3A, step-down switching controllers from Microchip Technology. The MIC2183BM is designed to provide smooth, low-noise ripple free output current to power microprocessors and other digital logic from input voltages up to 38.4V. It features a low-noise 900kHz fixed frequency architecture and a low-noise precision reference to offer high efficiency and low output ripple along with superior current-limit protection and fault-protection features.

The MIC2183BM contains integrated gate drivers, current-mode control, and voltage-mode control to allow best-in-class efficiency at any load. It also includes an integrated soft-start feature, which helps ensure proper turn-on of the converter. In addition, the MIC2183BM includes a unique voltage boost capability to ensure the desired output voltage is delivered to the load even at very light loads.

The MIC2183BM provides a total current limit, which means that it can provide better protection than current limited controllers. This is because if too much current is drawn, the MIC2183BM will limit the output current until the overload is cleared rather than just turning off the output. This prevents damage to parts or devices connected to the output.

The MIC2183BM features a voltage mode control architecture with a precision on-chip voltage reference to maintain tight line and load response. The voltage-mode control loop also helps reduce the magnitude of output ripple by providing tight loop compensation. This architecture provides a wide range of output voltage and current settings, which can be adjusted through external components.

The MIC2183BM\'s switching frequency can be selected via an external resistor, allowing the board design to be optimized for noise sensitive applications. The MIC2183BM also features built-in soft start and short circuit protection. The soft start feature sets an initial high-current limit to allow the controller to properly turn on, and the short circuit protection prevents the load from drawing an excessive amount of current.

In addition to its current-limiting features, the MIC2183BM also features a positive temperature coefficient (PTC) sensor. This sensor monitors the device temperature in order to protect it from an over temperature condition. If the device temperature exceeds its thermal limit, the PTC will kick in and reduce the current limit in order to prevent the device from being damaged.

The MIC2183BM is a versatile switching power-supply controller that can be used in applications requiring high-efficiency, high-output current, low output noise and high accuracy. It is ideal for powering personal computer motherboards, servers, and peripherals such as network switches, routers, and gateways.
