AX106670 is a packaged unit combining an AC/DC power supply, DC/DC converter and holds power factor correction. Featuring a small package size, it is ideal for a wide array of applications. This article will explore the various application fields of the AX106670 and discuss its working principles.

The high power density, wide input range, and standard footprint of the AX106670 make it useful in a variety of applications. This includes telecommunications systems, data-centers, industrial control systems, medical applications, it also as the power source of power exchanging equipment. Further, combined with its high efficiency and ultra-low acoustic noise it can be highly depended on for audio equipment. Additionally, the AX106670 brings additional features such as remote on/off, input voltage selection and over voltage protection.

The AX106670 is equipped with a proprietary technology called AC-DC operating in a zero-current switching (ZCS) operation mode. This allows operating the switch control stage (AC/DC) and the conversion stage (DC/DC) from a single cycle switch driver. The two stages are linked by a high frequency transformer, allowing the separation of the ground return of these two stages.

The operating principle of AC-DC/DC-DC for the AX106670 begins with the power factor correction, it uses an auto-correction algorithm to compensate the PFC circuit. This is done by monitoring the active power and the voltage at the DC/DC side, then regulate the PFC circuit and ensure all input power is effectively utilized in the process.

After PFC, the power is transferred from the AC/DC power supply stage to the DC/DC converter via the high frequency transformer. This transformer has multiple windings on the primary side and multiple windings on the secondary side, allowing the safe transfer of power gain and the isolation of input and output.

Finally, the AX106670 rectifies the input voltage and regulates the output voltage with two-stages DC-DC conversion. First, by utilizing an oscillator to generate a fixed frequency, and then ideally a feedback control circuit to maintain the output voltage accurate.

In conclusion, AX106670 is a perfect choice for high power density, wide input range, and standard footprint applications. Its integrated power factor correction and two-stage DC-DC conversion make it ideal for use in industrial systems, medical systems, audio systems, and more. Its unique AC-DC and DC-DC technologies and the high frequency transformer ensure the safe transfer of power gain and ensure the input power is fully utilized.
