SMI36-9-K-ST Application Field and Working Principle

The SMI36-9-K-ST is a high-efficiency DC-DC power adapter that converts AC input voltage to DC outputs. It features a universal AC input voltage range and a wide DC output range, making it a suitable AC/DC adapter for a variety of applications.

Application Field

The SMI36-9-K-ST is ideal for a wide range of high current applications, including industrial equipment, medical equipment, televisions, multi-media players, and other devices that require a reliable and efficient source of DC power.

Working Principle

The SMI36-9-K-ST utilizes full bridge rectification, followed by a high efficiency DC-DC switching converter. The AC input voltage is rectified by a Bridge Rectifier and then filtered by a Low Drop Out (LDO) regulator to provide an isolated and stabilized DC output. The switching converter then steps down the input voltage to the desired level. This switching converter uses Pulse Width Modulation (PWM) to achieve high efficiency with minimal power loss.

The SMI36-9-K-ST offers a wide DC output voltage range of 3.3V to 24V, up to 36A of output current, and is UL/EN/IEC 60950 safety certified. It also features active power factor correction, over-current, and over-temperature protection to ensure safe operation.

Conclusion

In conclusion, the SMI36-9-K-ST is a highly reliable and efficient AC/DC desktop and wall adapter ideal for a wide range of high current applications. It offers a universal AC input voltage range, a wide DC output voltage range, a high output current rating, active power factor correction, and protection features for safe operation.
