FAN5067MX

PMIC - Voltage Regulators - Special Purpose

The FAN5067MX is a voltage regulator designed to provide supply voltage management in portable electronic equipments. It is developed by Fan Mfg Co Ltd, and serves as a good starting point for providing power to portable products. It is an integrated circuit that helps achieve the desired voltage output by regulating the input voltage. It can be used in applications such as Laptops, DVD players, digital cameras and PDAs.

The FAN5067MX has a few unique features to its design such as low quiescent current, high efficiency and fast transient response. Low quiescent current means it requires less current to enable regulation of the input voltage. High efficiency means that it requires less energy to enable the regulation process, thus reducing the amount of energy wasted during voltage regulation. Its fast transient response feature helps it quickly provide additional current for it to deal with sudden electrical surges or changes in its environment.

The FAN5067MX is basically a high-performance first-order buck regulator with a current limit that is adjustable. It has an input range of 2.7V to 6.5V and a single output voltage adjustable range of 0.95V to 3.2V. It is also equipped with a silencing mode and ultra-low quiescent current, allowing it to shut down during low-power idle states.

The FAN5067MX is designed to use the PFM (Pulse Frequency Modulation) scheme for its current limit control to reduce its output ripple. This scheme uses an error amplifier to compare two signals and control the current limit accordingly. The error amplifier looks at the voltage level at the output terminal and the reference voltage set at the output terminal. With the PFM scheme, the current limit of FAN5067MX can be set accurately and the output ripple can be kept low.

The FAN5067MX also benefits from its built-in protection features, such as its thermal shutdown function and its over-current protection function. The thermal shutdown function will shut off the device if it starts to overheat and the over-current protection will shut off the device if it detects an over-current situation. This makes the FAN5067MX safe to use in varying conditions and environments.

The FAN5067MX is an excellent option for providing supply voltage management in portable electronic equipments. Its low quiescent current, high efficiency and fast transient response make it an ideal voltage regulator in applications like Laptops, DVD Players and PDAs. Its built-in protection features help protect it and equipments it powers in various conditions and environments.
