FAN5362UC33X is a fully integrated, advanced, non-synchronous buck regulator that can be used in a wide range of applications. The FAN5362UC33X is applicable to multiple input voltage applications and is capable of providing up to 3A output current. It provides a wide operating temperature range of -40 to +85 degrees Celsius and is available in the 3mmx3mm QFN package.

The FAN5362UC33X implements a high-efficiency switch-mode converter using efficient synchronous rectification and voltage regulation techniques. This offers the advantage of low quiescent current and extremely low output voltage ripple. It also offers high efficiency, both at no-load and highest full load.

The FAN5362UC33X has a switching frequency of up to 1.5MHz. This allows for fast load and line transient response. The device has an adjustable output voltage range from 0.6V to 5V, making it suitable for various voltage rail applications. Additionally, the device offers excellent light-load efficiency due to its low quiescent current.

The device also has two programmable current-limit settings, which can be used to ensure safe operation and prevent damage to the system. Additionally, the integrated soft-start function ensures that the output voltage rises at a controlled rate during start-up, reducing current surges and “inrush” current.

FAN5362UC33X also has built-in protective functions with over-current, over-voltage, over-temperature and under-voltage protection. This ensures safe operating conditions, improved reliability and longer product life. The protection circuitry will shut down the device if there is an influx of excessive current or if the temperature exceeds the specified safe limit.

The FAN5362UC33X is available with a maximum externally adjustable switching frequency of 500KHz, enabling the device to be efficiently used in high current applications. It has a high frequency spread spectrum feature, which reduces EMI (electro-magnetic interference). It also has an integrated power-good signal that alerts the system of an incorrect output voltage.

In conclusion, the FAN5362UC33X is an advanced, non-synchronous buck regulator designed for multiple input voltage applications. Its high efficiency, adjustable switching frequency and low quiescent current make it suitable for various voltage rail applications. In addition, the integrated protection features and spread spectrum feature make the FAN5362UC33X a reliable solution for many handheld and battery operated applications.
