The MP155GJ-P is an offline DC/DC converter IC designed to convert AC mains power to DC power outputs with a high efficiency while providing a regulated output voltage. It is an ideal solution for designs that require low cost, high accuracy, and high efficiency in a single IC.

The MP155GJ-P is specifically designed for applications that require a small form factor, high integration, high efficiency, and long life. It is capable of supplying up to 240 watts of power and accepts input voltages of 100 to 240V AC. The chip also has various protection features such as current limit, over-voltage protection, and over-temperature protection. It can be used in a variety of applications such as, grid tie inverters, industrial lighting, and portable electronics.

The primary benefit of the MP155GJ-P is its high efficiency, which reaches up to 87%. This high efficiency comes from a highly efficient design that includes a high-frequency transistor bridge rectifier and synchronous rectifying control circuit, which minimizes switching losses. It also has a low EMI rate of 20dB, which helps to reduce interference with other electronics and reduce the size of the transformer.

The working principle for the MP155GJ-P is similar to that of a traditional off-line switcher IC. The MP155GJ-P takes in a power input from the AC mains, rectifies it to DC, and then converts it to a regulated output voltage. This is done using a synchronous rectifying control circuit, a feedback loop, and a driver transistor, as well as various protection features. The MP155GJ-P also has a low-voltage start up feature which reduces start up time and minimizes the possibility of inrush currents.

The MP155GJ-P is an ideal choice for designs requiring a high efficiency and small form factor. Its ability to convert AC mains power to DC power with a high accuracy and efficiency makes it an excellent choice for a wide range of applications. Its features such as over-voltage protection, over-temperature protection, and low-voltage start-up make it a reliable and safe option.

In conclusion, the MP155GJ-P is a high performance offline DC/DC converter IC that provides a regulated output voltage with high efficiency and accuracy. Its small form factor and protection features make it an ideal solution for designs that require a low cost, high integration, and long life. It can be used in a variety of applications requiring a reliable and safe solution for power conversion.
