FAN7680N

The FAN7680N is a high performance, highly integrated power supply controller and monitor IC. It is a PMIC (Power Supply Controllers, Monitors) that supports up to 20 Step-down (buck) outputs and up to 5 linear regulators. It is designed to provide a wide range of power delivery and monitoring services in a compact package. The FAN7680N provides superior performance in applications such as automotive, industrial, consumer, home and other general purpose power supply systems.

The FAN7680N offers many advantages to system designers. It is very small in size (only 5mm x 6mm) and consumes low power. It comes with on-chip features that enable it to monitor, regulate and deliver power efficiently and accurately without the need for external components. It is highly integrated allowing for a wide range of features and functions to be implemented in a single chip. It also has integrated protection features for overcurrent and voltage protection.

The FAN7680N has a very simple and efficient working principle. It has a supply voltage rail that is monitored by a precision voltage regulator. When the rail voltage drops, the regulator activates and boosts the supply voltage back up to the desired threshold. The output voltage is then set by a set of programmable rail dividers. The dividers are set at a higher voltage than the input voltage to ensure that the desired output voltage is achieved. The dividers can also be adjusted to adjust the desired output voltage.

The FAN7680N has programmable overvoltage, undervoltage, current limit and thermal limit settings to improve the protection of the device and the system. The device also integrates multiple phase-locked loops to reduce ripple on the output voltage. The phase locked loops are responsible for maintaining the phase relationship between the input and output voltage signals.

The FAN7680N is used in many different applications. It is used for powering and monitoring of a variety of different systems including automotive, industrial, home and other general purpose power supply systems. It is also used for providing voltage regulation for USB ports, buffered voltage regulators and linear voltage regulators. It can be used for driving high power switching regulators, power factor correction and over-current protection (OCP) devices.

In conclusion, the FAN7680N is a high performance, high-integration power supply controller and monitor that provides superior performance in applications requiring a wide range of power delivery and monitoring services. It is a very small size, consume low power and integrates a wide range of features and protection mechanisms. It is ideal for automotive, industrial, consumer and home applications. Its working principle is based on a voltage monitor rail and a precision voltage regulator that ensure a desired output voltage, as well as multiple phase-locked loops that reduce current ripple and maintain the phase relationship between the input and output voltage signals.
