FX004 application field and working principle

Introduction

The FX004 is a Voltage Regulator designed for special applications. It is a highly integrated device that has been designed to provide all the features and functionality necessary to meet the stringent requirements of a large family of applications.

The FX004 is ideal for applications that require high power conversion efficiency, low input voltage, low output voltage, wide input voltage range, high current delivery, and robust design. It is capable of operating from both 24V and 48V input voltage sources, and it can be easily configured to output both 1.8V and 3.3V output voltages, making it the perfect solution for a wide range of applications.

Application Field

The FX004 is suitable for use in a wide range of applications including:

• Mobile Phone Charging
• Computers and Servers
• Industrial and Automotive Equipment
• Medical and Military Applications
• High Voltage Motor Drives

The FX004 is particularly well suited to applications where high current delivery, high efficiency and high reliability is essential. It is also well suited to applications that require wide input voltage ranges and low output voltage levels.

Working Principle

The FX004 utilizes an advanced Voltage Regulator architecture, known as a switched-capacitor voltage converter. This voltage conversion process starts with a capacitor which is charged up to the higher input voltage of 48V. This energy is then stored in the capacitor and converted into a lower regulated output voltage. The Voltage Regulator then switches the capacitor to discharge the stored energy at the required output voltage. This process is repeated every cycle, resulting in a steady output voltage from the FX004.

The FX004 has two resistors external to the device, known as the load and feedback resistors. These two resistors work together to regulate the output voltage of the FX004. The load resistor is used to set the current that is drawn from the regulator and the feedback resistor is used to adjust the output voltage of the regulator.

The FX004 can also be used as an isolated voltage regulator. This is particularly useful in applications where it is impossible or undesirable to have a direct connection between the input and output. The FX004 provides isolation between the input and output, enabling the device to be used in sensitive or hazardous applications.

Conclusion

In conclusion, the FX004 is an ideal solution for a wide range of applications requiring low voltages, high efficiency power conversion, and reliable operation. The device is easy to configure and can be used in both isolated and non-isolated configurations. The FX004 is a highly advantageous Voltage Regulator for applications that require reliable, efficient and cost-effective power conversion.
