Application Field for MIC2141BM5-TR

The MIC2141BM5-TR is an ideal choice for many applications wherever a high-efficiency dual non-isolated DC/DC step up energy converter is required. It is especially suited for embedded systems, telecom power systems, servers, embedded storage devices and motor controllers. Its wide input voltage range of 4.5 V to 28 V makes it a suitable choice for powering various devices such as Flash memory cards, mSATA SSDs, embedded NAND Flash products and other similar devices.

It has very low shutdown current of 6 μA and very low current (0.85 mA typical) which makes it very energy efficient. The module offers reliable high current transfer with minimum energy losses. It features a wide input common mode support and requires very few external components for effective functioning.

Working Principle of MIC2141BM5-TR

The basic working principle of the MIC2141BM5-TR is based on a synchronous buck converter. It works by converting a higher input voltage to a lower output voltage, which is maintained by a controller circuit. The controller is responsible for the regulation of output voltage and so the output voltage is adjustable and can be changed depending on the application requirements.

The MIC2141BM5-TR has an on-board controller, with pre-programmed voltage down-conversion ratios and slew rates, allowing it to adapt quickly to changing load conditions. It also has fault protection capabilities, providing protection against over-voltage, under-voltage and over-temperature conditions.

The MIC2141BM5-TR also features a proprietary Advanced Fault-Protection circuit that provides control and monitor functions, allowing the system to react to and identify fault states quickly without requiring manual reset. This feature is especially useful in safety applications and improves overall system reliability.

Conclusion

The MIC2141BM5-TR is a high-performance power module and is suitable for many applications as a dual non-isolated DC/DC step up energy converter. It has wide input voltage common mode support, very low shutdown current and very low current, making it very energy efficient. It also features an on-board pre-programmed voltage down-conversion ratio and slew rate, making it suitable for quickly adaptable applications. It is an ideal choice for embedded systems, telecom power systems, servers, embedded storage devices and motor controllers.
