DC DC converters provide various solutions in the process of voltage or current conversion, and can be widely used in batteries, mobile devices, various system circuits, etc. MI-220-IW-F2 is a typical DC DC converter with many advantages. Its application field and working principle will be introduced in this article.

Application Field of MI-220-IW-F2

MI-220-IW-F2 is a 2W, regulated, isolated DC DC converter which can operate with an input range between 4.5V to 14Vdc and provide an output of 5Vdc at a power rating of 2W. It is ideally suited when you need to power your low power application from a variety of input source and it could be a great choice for industrial control devices, instrument and device on the rig site, and mobile application, such as the new generation mobile phone.

Working Principle of MI-220-IW-F2

The working principle of MI-220-IW-F2 DC DC converter is based on the Buck Converter power topology. It contains a switch, an inductor, a diode and a capacitor. When the switch is turned on, the input voltage source will be connected to the inductor, then the energy stored in inductor become a magnetic field. When the switch is turned off, the flow of electricity reverse, and the energy stored in the magnetic field will be released and pushed against the diode. This allow current to flow through the capacitor to the output as regulated voltage. The capacitor at the output will control the output voltage. This process repeating itself and cause the change of voltage level. The speed of switch is determined by a feedback loop which detecting the output voltage , and adjust the ‘on’ and ‘off’ cycle of switch.

Features of MI-220-IW-F2

MI-220-IW-F2 has a number of unique features that make it an excellent choice for DC-DC conversion. It has a wide 2:1 input voltage range, good efficiency (up to 93%), excellent EMI performance, a standby current of only 7mA, and a low-profile SIP package. The high efficiency of MI-220-IW-F2 can reduce energy loss and reduce system thermal and long-term reliability, making the product more reliable. Its wide input voltage range ensures that it can work properly even when the input voltage is unstable, while its advanced EMI circuit design meets the EMI testing requirements for the typical environment.Meanwhile, the low standby current ensures long-term protection of the power source and keeps components cool, thereby providing higher reliability and longer service life. In summary, MI-220-IW-F2 is a reliable, efficient and economical choice for a variety of DC-DC conversion applications.

Conclusion

In conclusion, MI-220-IW-F2 is a 2W, regulated and isolated DC DC converter which can be used in industrial control devices, instrument and device on the rig site, and mobile application. It can operate with an input range between 4.5V to 14Vdc and provide 5Vdc as output. It occupies a low-profile SIP package and has features such as good efficiency, excellent EMI performance, low standby current, etc which make it an ideal DC DC converter in many applications.
