FAN5094MTCX Application Field and Working Principle

The FAN5094MTCX is a voltage regulator IC, specifically classified as a special purpose IC, which is manufactured by Fairchild Semiconductor. The device is typically used for isolated power supply applications with a single output and tracking/regulation. It includes several functions for monitoring, controlling, and sequencing of SPI-programmable power supplies, as well as providing feedback of various parameters from the system.

Features

The FAN5094MTCX has several features that make it suitable for isolated power supply applications. These include a wide operating temperature range of -40°C to +85°C, an input voltage range of 8V to 32V, and an output voltage range of 0.65V to 17V. Additionally, the device supports an additional 3.3V main supply and has a current monitor output, adjustable voltage and current fault limits, and under-voltage lockout (UVLO).

Functions and Applications

The FAN5094MTCX has several main functions, including voltage and current regulation, voltage and current monitoring, and line tracking. The voltage and current regulation features ensure that the output voltage and current are monitored and kept at the specified value. Voltage and current monitoring allow the user to monitor the voltage and current levels of the system, while the line tracking feature enables the device to regulate the output voltage with both negative and positive temperature coefficients.

The FAN5094MTCX can be used in many isolated power applications, such as isolated switching power supplies, LCD backlight drivers, embedded power supplies, and power converters. The device is particularly useful for high-performance applications that require accurate and reliable performance, such as those in consumer, communication, and industrial electronics.

Working Principle

The FAN5094MTCX works by containing two internal DC-DC boost converters, one on each side of the chip. The chip takes in a DC input voltage which is boosted to a much higher voltage. This higher voltage is then fed back to the input, and a feedback loop is used to regulate the output voltage. The chip also contains voltage and current protection features, which ensure that the device is protected against over-voltage, over-current, and under-voltage conditions.

The FAN5094MTCX also features SPI programming, which allows the user to program the device to the specific requirements of their application. This includes setting over-voltage, over-current and under-voltage thresholds. The chip also provides comparator and tracking/regulation modes, which enable the system to be synchronized and fine-tuned for various different output scenarios.

Conclusion

The FAN5094MTCX is a voltage regulator IC that is suitable for isolated power supply applications. The device has several features including a wide operating temperature range, wide input voltage range, adjustable voltage and current fault limits, and SPI programming. Additionally, it includes two internal DC-DC boost converters and voltage/current monitoring as well as line tracking features, making it suitable for high-performance applications.
