The LFA75F-5 is an AC/DC converter. It is a highly efficient single-phase isolated microinverter designed to convert AC power into a DC power supply. This can be used in various applications such as solar power conversion, home energy usage, and automotive applications.

Power Conversion Specifications

The LFA75F-5 has a wide input voltage range from 85 to 265 volts that can power a wide variety of products and applications. It has high efficiency of 94%, coupled with a compact form factor and high power density. The output voltage range is adjustable from 0.7V to 7V, with an adjustable output power range from 1 to 75 watts. The maximum input frequency is 60Hz and the maximum output frequency is 300kHz.

Features

The LFA75F-5 has multiple built-in safety features to protect components and equipment. The converter also has a built-in EMI filter that meets EN 55032 which is a product level conducted emission standard. Also, it has a remote control input and output terminals that allow it to be used in remote monitoring applications.

Working Principle

The LFA75F-5 works by using a full bridge rectification circuit to convert AC power into a DC power supply. This is done by using four MOSFETs, two of which are used for positive rectification and two used for negative rectification. The AC input voltage is then divided into two AC half cycles, and each MOSFET pair is used for respective rectification. The output voltage is adjustable with the help of the external control voltage, which is connected to the controller. A control loop is used to control the output voltage to the desired level. In addition, a wide range of protection functions including over voltage protection, short circuit protection, and thermal shut down are also built into the device.

Applications

The LFA75F-5 can be used in a wide range of applications such as industrial, solar, automotive, and consumer electronics. It is used in products such as solar panels, laptop adapters, power banks, LED drivers, and many more. It is also used in small home appliances such as vacuum cleaners, electric fans, and air purifiers that can benefit from a reliable, efficient power source.

Benefits

The LFA75F-5 offers many benefits, such as its high efficiency, small form factor, and wide input voltage range. It is also very reliable and is designed to provide a long operational lifespan. Finally, it has multiple built-in safety features that protect against overloads and other damaging conditions.
