FSQ0165RL is a high-performance Power Management Integrated Circuit (PMIC) specifically designed for AC-DC converters and offline switchers. It is equipped with a variety of power management functions such as over-voltage, over-current, over-temperature protections and switching frequency control.

The FSQ0165RL is capable of regulating any input voltage within a wide range, from 9V to 160V, thus making it suitable for a variety of offline applications. The maximum output power is set to 65W and the over-temperature protection is set to the maximum of +127 degree Celsius. Apart from that, the operating temperature should never exceed +85 degree Celsius to ensure a stable and reliable operation over time.

When it comes to its working principle, the FSQ0165RL uses a combination of linear and switching regulation techniques. First, the input voltage is read by the ADC and converted into a digital value. This value is used by the PWM controller to regulate the output voltage within a certain range. The PWM controller then drives the switching transistor which is responsible for converting the input voltage into an output one.

A few special features of the FSQ0165RL worth mentioning include its brown-out protection and soft-start function. The former is able to detect and prevent any sudden changes in the input voltage, while the latter reduces the inrush current during start-up, thus decreasing the possibility of overloads and extended start-up time. In addition, the FSQ0165RL also supports a wide range of output voltage modes, from constant voltage to constant current.

Overall, the FSQ0165RL is a perfect choice for AC-DC converters and offline switchers, thanks to its exceptional performance and reliable power management features. It is capable of regulating any input voltage within a wide range, while its over-temperature and over-current protections ensure that the system remains safe and stable at all times. With its support for multiple output voltage modes, the FSQ0165RL is the optimal PMIC solution for any application.
