PMIC - AC DC Converters, Offline Switchers, is an important part of Power management integrated circuits (PMICs). FSQ0765RSLDTU application field and working principle is an important topic in the field because it can help to better understand how the device works and its applications.

The FSQ0765RSLDTU is an integrated circuit that is specifically designed for AC-DC converters used in offline switcher systems. This device is used to control power factor correction (PFC) in offline switcher systems. It is specifically designed to meet the requirements of high current applications such as LED lighting and SMPS applications.

The basic function of the FSQ0765RSLDTU is to control the power factor correction in the system. It will regulate the input voltage and current, and ensure that the desired power factor is maintained. This is done by feeding the correct voltage into the input of the system and maintaining the correct current level. The device will use the monitored power feedback to limit the input current and thus regulate the power factor.

In terms of operation, the FSQ0765RSLDTU will use a variety of techniques for power factor correction. These include switched-mode PFC, zero-wall PFC and active PFC. The switched-mode PFC is the most common type used in offline switchers and is designed to maintain the power factor of the system. Zero-wall PFC and active PFC is less common and is used in situations where high power factor is not as important.

The FSQ0765RSLDTU can also be used to provide over-voltage protection to the system by detecting excessive input voltages, and activating protection circuitry to limit the voltage and current. This can be invaluable in situations where the system is exposed to surges or other hazardous occurrences.

The working principle of the FSQ0765RSLDTU is quite simple and straightforward. The device has an internal voltage reference and a current sensing circuit. This will measure the input voltage and current and compare it against the internal reference. Based on this comparison, the device will adjust the power factor by controlling the input voltage and current.

The applications of the FSQ0765RSLDTU are broad and covers a wide range of power management needs. From LED lighting and other high-power applications to low-power applications, the device can provide accurate power factor control and protection. Additionally, the device is suitable for for smart power supply systems, industrial equipment, and general purpose AC-DC switchers.

In conclusion, the FSQ0765RSLDTU is an integrated circuit specifically designed for AC-DC converters in offline switcher systems. It provides a variety of features and benefits, including power factor control and protection, as well as over-voltage detection. Its applications range from LED lighting and high-power applications to more low-power applications such as smart power supplies and industrial equipment. In addition, its working principle is simple and straightforward, making it an effective and reliable solution for a variety of power management needs.
