PMIC (Power Management Integrated Circuit) devices are becoming increasingly important in today’s power management designs. One of the most important and widely used PMICs are AC DC converters, offline switchers, and FAN7602BMX. In this article, we will discuss the application field and working principle of FAN7602BMX.

The FAN7602BMX is a monolithic CMOS integrated circuit, which is used to provide energy-efficient, space-saving, and reliable offline AC/DC power conversion solutions. It is designed to operate from an 85-265V AC/DC input source, and can provide up to 250mA of output current. This IC is ideal for a number of industrial, consumer, and automotive applications that require efficient energy conversion from AC/DC input sources.

The application field of the FAN7602BMX IC is wide ranging, and includes LED lighting, industrial automation, computer peripherals, industrial robotics, and others. The IC is also suitable for motor drive circuits, motor control circuits, and fan control circuits. Additionally, the FAN7602BMX IC can be used in high power applications, such as server and power supply design, and can also be used as a DC/DC converter.

The working principle of the FAN7602BMX IC consists of two integrated components- an off-line power switch and an off-line flyback converter. The power switch consists of two high voltage independent power switches and a low-side driver. When the AC input voltage is applied to the IC, the power switches are turned on, causing the current to flow through the source, the MOSFETs, and the output. The voltage on the output will then create a supply for the off-line flyback converter. The output voltage is controlled by the current-mode adaptive jittering control circuit.

The off-line flyback converter is responsible for the conversion of the AC/DC input into the desired output voltage. It consists of a transformer and an inductor, which together form a closed-loop feedback circuit. The transformer is connected between the input and the output, and the current flows through the inductor on each cycle. The transformer is then switched off, allowing the current to be stored in the inductor, and then the inductor is switched off, allowing the current to flow back to the input. The result is an energy conversion from the input AC/DC voltage to the desired output DC voltage.

The FAN7602BMX is an energy-efficient and reliable solution for offline AC/DC power conversion needs. It is designed to support a wide range of industrial, consumer, and automotive applications that require efficient energy conversion from AC/DC input sources, as well as high power applications, such as server and power supply design. The working principle of the IC consists of two integrated components- an off-line power switch and an off-line flyback converter, which together form a closed-loop feedback circuit to provide the desired output voltage.
