ETA2822E8A

The ETA2822 is a total solution IC specifically for high voltage USB charging applications. It includes a wide input range, high - efficiency, and high frequency DC - to - DC step - down switching regulator that is capable of delivering up to 3.1A of output current. The DC - DC in ETA2822 is a current mode converter with a fixed - frequency that is externally adjustable. There is also a cable resistance compensation feature that allows users to adjust the output voltage to compensate for the voltage drop due to cable resistance. An OVP function protects the IC itself and its downstream system against input voltage surges. With this OVP function, the IC can stand off input voltage as high as 42V, making it an ideal solution for industrial applications such as smart powermeters as well as automotive applications. In automotive systems, power comes from the battery, with its voltage typically ranges between 9V and 24V. Including cold crank and double battery jump - starts, the minimum input voltage may be as low as 4V and the maximum up to 36V, This makes ETA2822 ideal for the automotive application.
