Introduction

The MIC2586R-2YM TR is a high-performance, two-phase buck hot swap controller for AC/DC power applications. It offers a complete hot swap capability in a 5-18V input range and provides a complete suite of safety features, including multiple over voltage protection (OVP) levels, current limit protection (CLP) levels and input under voltage protection (UVLO). This hot swap controller features a highly-integrated design and is suitable for a wide range of applications, including system power supplies and multitasking ATX power supplies.

Working Principle

The MIC2586R-2YM TR hot swap controller is based on an improved, two-phase control architecture with a synchronous rectification buck converter topology. Its low-profile design and built-in shutdown features make it suitable for space-limited power supply solutions.This converter device focuses on efficiency, heat dissipation and voltage noise reduction. The two-phase control allows for reduced switching frequency, resulting in better power efficiency and smaller power components. In addition, the device also provides a higher average current rating and does not rely on the traditional current-sense technique for power monitoring. Instead, a high-efficiency buck converter uses constant-current control technology that reduces power dissipation and supports higher load currents.The MIC2586R-2YM TR offers a comprehensive set of protection features, such as multiple over voltage protection (OVP) levels, current limit protection (CLP) levels and under voltage protection (UVLO). It also offers a unique turn-off ramp generator, which provides a gradual shutdown of the system to minimize power losses.

Applications

The MIC2586R-2YM TR is suitable for a variety of applications, including system power supplies, mobile devices, hard disk drives, optical disk drives, PDAs, and hot-swap solutions. This power converter can also be used in conjunction with traditional AC/DC power supplies, such as linear regulators, CISPR-22 compliant switch mode power supplies (SMPS), and PC power supplies.The built-in protection circuitry of the device also makes it suitable for applications that require a higher degree of safety and reliability. For instance, the MIC2586R-2YM TR can be used in medical and mission-critical systems, as it is capable of providing protection against over-current, over-voltage, and thermal conditions.The device also offers a number of advantages for automotive applications. Its low-power standby mode and over temperature protection make it ideal for applications in automobiles, where the ability to operate over a wide temperature range is important. The device is also designed to meet the requirements of high sound emissions and minimal EMI radiation, making it suitable for noisy automotive applications.

Conclusion

The MIC2586R-2YM TR is a high-performance two-phase buck hot swap controller for AC/DC power applications. It provides a complete hot swap capability that can be used in a wide range of applications, including system power supplies and multitasking ATX power supplies. It also offers a comprehensive set of protection features, such as multiple OVP levels, CLP levels and UVLO. This device is suitable for applications that require a higher degree of safety and reliability, as it supports over-current, over-voltage, and thermal conditions protection. In addition, its low-power standby mode and wide operating temperature range make it ideal for automotive applications.
