Introduction to DC DC Converters
DC/DC converters are a class of power electronics devices used to modify/regulate the form of voltage, power, and current in devices connected to a DC power supply. This is how they are utilized: incoming power from the source is first converted from direct current (DC), to alternate current (AC) typically using an oscillator driving an inductor; the AC current then gets converted to a lower DC voltage and/or higher DC voltage or higher current than it originally came in with, via a transformer; finally, the DC voltage is regulated through a series of rectifiers and/or filters, to the desired output level.NE12S0A0V20PNFA DC/DC Converter
The NE12S0A0V20PNFA is an ultra-wide input voltage range 12 W DC/DC converter from TDK Corporation. The product is designed to take in an input of 6V-75V voltage range to deliver 12W of output at 20VDC, with a power efficiency as high as 90%. It is encased in a hermetic metal case, making it suitable for harsh environment applications such as railway, medical, and military etc.Application Field
The NE12S0A0V20PNFA DC/DC converter can be used to convert a high input voltage into the regulated lower output voltage at a high power conversion efficiency rate of up to 90%. This type of converter is suitable for harsh environment applications such as railway, medical, and military etc, due to its hermetic metal case, wide input voltage range, and high power conversion efficiency rate.Work Principle of NE12S0A0V20PNFA
The NE12S0A0V20PNFA employs a step-down switching converter topology, which relies on the principles of inductors and capacitors to convert the incoming DC voltage of 6V-75V to an output voltage of 20VDC. The device begins with an input of 6V-75V DC voltage, which is then passed through an oscillator driving an inductor. This oscillator is used to convert the alternating current (AC) to a lower dispersed frequency, which is then fed to an output junction. A transistor is then used to switch the junction in order to adjust the output voltage by utilizing the change in current. The output voltage will then pass through a rectifier and a filter or a voltage regulator, to reduce noise or to set the desired output voltage level. The regulated output voltage goes through the transformer, which then passes it to the output device. Finally, the power conversion efficiency is achieved by utilizing a synchronous MOSFET rectifier, and a PWM (pulse width modulation) control. These two components compensate for the voltage drop caused by the output current. The output voltage of 20VDC is limited by the transformer during the PWM control, thus obtaining an optimal power efficiency.Conclusion
The NE12S0A0V20PNFA DC/DC converter is an effective solution for applications that require efficient step-down conversion from a higher input voltage to a lower output voltage with a high power efficiency rate. Owing to its hermetic metal case and wide input voltage range, it is suitable for many harsh environment applications such as railway, medical, and military etc. It utilizes an oscillator driving an inductor, to convert the AC current to a lower dispersed frequency; then, a transistor is used to switch the junction in order to adjust the output voltage; finally, a synchronous MOSFET rectifier, and a PWM (pulse width modulation) control are used to regulate the output voltage and reduce the voltage drop, thereby achieving a high power efficiency rate of up to 90%.The specific data is subject to PDF, and the above content is for reference
