The MIC2204BMM is a highly integrated power-management IC (PMIC) for voltage regulating applications. It is a DC DC switching regulator that integrates both high voltage and low voltage linear regulators on a single chip, providing a high degree of flexibility and cost savings.

The MIC2204BMM is designed to operate from an input voltage range of 4.8V to 20V. It can accept input voltages up to 50V, making it suitable for a wide range of applications including telecom, automotive, industrial and portable systems.

The MIC2204BMM has two buck regulators that can provide up to 8A or 8.8A of output current. It also has two linear regulators that can provide up to 2A of output current. The linear regulators are capable of tracking the buck regulator N-fets drain voltage as well as supplying a level of “load disconnect” under certain conditions.

The MIC2204BMM is able to operate in either switching or linear mode. In switching mode, the PMIC operates with an output frequency of 1.5MHz. In linear mode, the output frequency of the regulator is adjustable from 0.5Hz to 1.5MHz. Both modes offer a wide range of features and functions.

The MIC2204BMM includes an adjustable overload protection circuit. This provides protection against overload, over-voltage and over-temperature conditions. The circuit can also monitor inputs and outputs to detect and shut down the circuit in the event of an over-load or over-voltage condition.

The MIC2204BMM provides protection against short-circuits, over-temperature and over-voltage conditions. It also has an auto-foldback mode where the output voltage is automatically reduced when the output current exceeds the programmed level. This feature also helps to reduce output power dissipation.

The MIC2204BMM is designed to operate in either a continuous or a discontinuous conduction mode (CCM or DCM). This allows the user to switch between the two modes to optimize efficiency and reduce power dissipation.

The MIC2204BMM includes a programmable soft-start circuit. This allows the output voltage to be gradually ramped up, reducing in-rush current and protecting the power supply in hot-swap applications.

The MIC2204BMM is available in a space-saving 5mm x 5mm QFN package with both exposed and non-exposed pads. It is offered in both industrial and automotive grade versions, allowing for improved temperature performance and design flexibility.

The MIC2204BMM is an ideal solution for applications that require a high efficiency, robust, and feature-rich solution in a compact form factor. It is an ideal choice for DC-DC converters, portable devices and automotive applications.
