Power conversion is a key part of any electronic system. In order to properly power a system, an appropriate power conversion is needed to ensure the system not only runs properly, but also remains efficient. The FSQ321LX is an offline PWM flyer switch, providing power conversion between a DC supply and a DC load. This PWM flyback switch includes over-voltage and over-current protections, making it a reliable choice for power conversion within any system.

Overview

The FSQ321LX is a Flyback switch with an integrated control IC. It has an input voltage range of 27V to 60V and an output voltage range of 30V to 400V. It features power MOSFET and IGBT technology, allowing it to achieve high efficiency, low noise operation, and a wide range of output power. The device also features over-voltage and over-current protection through integrated circuitry. This protection helps ensure that the system is not overloaded, and that the switch stays within its design limits.

Application Field

The FSQ321LX is well-suited for a variety of applications, including offline DC to DC converters, switching voltage regulators, motor control systems, lighting systems, and more. It is especially useful for applications that require high efficiency and a wide range of output power. It is also a good choice for controlling power overloads, as the integrated protection ensures that any overloading is immediately detected and automatically corrected.

Working Principle

The FSQ321LX operates on the principle of flyback switching. When an input voltage is applied, an oscillator is enabled and an output voltage is generated. This output voltage is regulated by a comparator IC and a reference voltage. Once the reference voltage is reached, the oscillator turns off and the output voltage begins to fade. This feedback loop ensures that the output voltage remains within the designated range. When the output voltage reaches a predetermined level, the oscillator turns on again and the cycle repeats.

Conclusion

The FSQ321LX is a reliable and efficient offline PWM flyback switch. It is well-suited for a variety of applications, including DC to DC converters, switching voltage regulators, motor control systems, lighting systems, and more. It features high efficiency, low noise operation, and a wide range of output power. In addition, it includes integrated over-voltage and over-current protection, which helps ensure a safe and reliable operation. Overall, the FSQ321LX is a great choice for power conversion within any system.
