The FSQ500SL is an integrated circuit (IC) component that offers a range of key features suitable for various applications. It is a high-voltage switch power supply controller designed for use in power converters and offline power systems. Here is an overview of the FSQ500SL and its notable features:
1. High Voltage Capability: The FSQ500SL can handle a high input voltage range of up to 650V, making it suitable for applications that require a wide range of input voltage levels.
2. Power Factor Correction (PFC): It supports active power factor correction, which enables efficient power conversion and compliance with international power quality regulations. PFC ensures the efficient utilization of energy and reduces harmonic distortions.
3. Multi-Protection Features: The IC is equipped with a comprehensive set of protection features to safeguard the system against faults and abnormal conditions. It includes overvoltage protection (OVP), overcurrent protection (OCP), over-temperature protection (OTP), and brown-out protection (BOP).
4. Current Mode Control: The FSQ500SL employs a current mode control technique, which provides precise regulation of the output voltage and ensures stable power supply operation. The current mode control also offers inherent compensation for feedback loop stability.
5. Low Standby Power Consumption: It incorporates a burst mode operation to reduce idle power consumption at light loads. This feature helps to enhance energy efficiency and reduce overall standby power consumption, making it suitable for applications with varying load demands
