Power factor correction (PFC) is an important element in electrical systems as it helps rectify power signals, reduce power consumption, and minimize electrical losses. The FAN4800IN_G is a highly efficient, buck-boost voltage converter that provides power factor correction and operates over a wide input voltage range. The device features the flexibility to support a wide range of input voltages while delivering the required output voltage in an application.

The FAN4800IN_G can operate over an input voltage range of 12V to 48V and deliver an output range of 1.8V to 36V. The device features an integrated primary-side, real-time, synchronous PFC controller with pulse-width modulation (PWM), and an asynchronous buck-boost power stage with a low quiescent current to ensure high power efficiency and high power factor. The device also offers adjustable frequency control for user-defined frequency ranges, leading to a lower probability of harmonic distortion.

The PFC feature in the device allows it to reduce harmonic distortion and Power Factor (PF) of the power supply, resulting in greater efficiency. As the device senses and regulates the input voltage, it ensures reliable performance and therefore eliminates the possibility of over or under voltage faults. This allows the device to provide precise voltage control over a wide input range, providing well-regulated output power.

The FAN4800IN_G also offers short-circuit protection, over-temperature protection, and under-voltage lockout (UVLO) functions. These features ensure safety by preventing reverse current flow, overheating, and over current. Additionally, the device features an integrated output over-voltage protection (OVP) function, which allows the user to set an upper limit on the output voltage to ensure reliable and safe operation.

In terms of power efficiency, the FAN4800IN_G achieves 95.5% average efficiency (at 115Vac) and can achieve a power factor of > 0.98. This makes it an excellent choice for applications which require reliable, high- power solutions with minimal power losses. This device is thus ideal for datacom and telecom applications, as well as industrial applications, such as industrial control circuit power supplies, milk machines, chemical pumps, display cables, etc.

In summary, the FAN4800IN_G is an integrated power factor correction (PFC) solution with buck-boost topology. The device features an integrated primary-side, real-time, synchronous PFC controller and an asynchronous buck-boost power stage. It operates over an input voltage range of 12V to 48V and delivers an output range of 1.8V to 36V. It offers adjustable frequency control for user-defined frequencies and short-circuit protection, over-temperature protection, and UVLO functions, as well as an integrated output OVP function. It also offers a high power efficiency and a power factor of > 0.98, making it an excellent choice for reliable, high-power solutions in applications for Datacom and Telecom, as well as industrial control circuit power supplies, milk machines, chemical pumps, display cables, etc.
