The MIC2182YM is a high frequency, high efficiency, synchronous buck regulator integrated circuit (IC) component manufactured by Micrel Inc. It is designed to deliver a constant voltage output with a maximum load current of 2.5 Amps. The MIC2182YM is well-suited for use in a wide range of applications including computing, consumer electronics, and industrial devices.
One of the key features of the MIC2182YM is its high efficiency conversion capability. With the synchronous rectification technology employed in this IC, it achieves excellent power conversion efficiency while operating at high switching frequencies. This makes it highly suitable for battery-powered devices as it minimizes power losses and helps extend battery life.
The MIC2182YM is capable of operating over a wide input voltage range, typically from 4.5 to 28 Volts, enabling it to be used in various power supply configurations. It also offers a selectable fixed frequency PWM mode or a pulse-skipping mode for improved light-load efficiency. This flexibility makes it adaptable to different system requirements and enables designers to optimize performance based on the application.
Additionally, the MIC2182YM features built-in protection mechanisms to ensure the safety of both the IC and the connected load. These protections include over-temperature shutdown, hiccup mode short-circuit protection, and overvoltage protection. These safeguards make the IC highly reliable and help protect the circuit from damage in case of abnormal operating conditions
