MIC2182-5.0YM-TR is a high efficiency, synchronous, step-down switching regulator controller which provides a highly efficient and extremely simple power supply solution. It is ideal for cost-sensitive designs that require a high efficiency, easy-to-implement power solution.

Application Field

The MIC2182-5.0YM-TR is built on the CompactPower™ process technoology, and is capable of delivering up to 5 A of output current with a regulated output voltage of 5.0 V. The device has a wide input voltage range of 4 to 28 V, making it suitable for applications such as portable devices, automotive and industrial control systems, point of sale equipment, and many other power system designs.

Working Principle

The MIC2182-5.0YM-TR utilizes a synchronous, step-down DC/DC controller which enables it to achieve over 95% efficiency with very little external components. It incorporates an internal 250 kHz oscillator and three powerful N-FET drivers along with logic circuitry required for low noise, fast transient response, and constant frequency PWM. The device also includes a low voltage protection, thermal overload, and user adjustable current limit features for reliable and safe operation. The MIC2182-5.0YM-TR also features an input current-bottoming control which reduces the switching jitter during light to medium load conditions.

The MIC2182-5.0YM-TR has two forms of protection to ensure reliable operation. Since the device works with high switching frequencies, the device incorporates an over current protection circuit to ensure safe operation and prevent the device from overloading. Additionally, a thermal overload protection circuit is also included to ensure that the device does not overheat and damage the components.

Conclusion

The MIC2182-5.0YM-TR is a high efficiency, synchronous, step-down DC/DC controller which enables low cost, high efficiency power solutions. It is ideal for cost-sensitive applications that require a simplified power solution with high efficiency. The device has an extended input voltage range and incorporates multiple protection features to ensure reliable operation.
