The XR71211EVB evaluation board is a key piece of equipment for anyone looking to optimize the performance of their power converter design. As part of a larger family of evaluation boards, the XR71211EVB is designed for DC/DC & AC/DC (Off-Line) SMPS applications.

This evaluation board is equipped with an integrated switching regulator circuit that is capable of delivering up to 40A output current with up to 11V input voltage. The board itself consists of several components, including the IC controller XR71211, integrated circuit driver XR70160, MOSFETs, a high current coil, multiple capacitors, a ground connection, and a heatsink. These components work together to offer a powerful solution for DC/DC & AC/DC (Off-Line) SMPS applications.

The working principle behind the XR71211EVB is relatively simple. The integrated circuit controller XR71211 acts as the main controller, while the integrated circuit driver XR70160 and the MOSFETs control the flow of the electricity. The high current coil receives the input voltage, while the output voltage is taken from the capacitors. The XR71211EVB works with a single, fixed frequency pulse width modulation to convert the input DC voltage into the desired output voltage or current.

In order to use the XR71211EVB efficiently, it must be connected to two power rails, namely an input voltage and a ground connection. The input voltage should be at least 11V, while the ground connection should be placed near the input rail. The XR71211 controller is connected to a pin in the controller header, with pins 4 and 5 being used for the PWM signal input and pin 3 being the PWM enable pin. The driver XR70160 is connected to another pin in the header, with the load pin connected to the positive output of the board and the other two pins being connected to the ground.

The XR71211EVB is an ideal solution for both professionals and hobbyists who require an efficient and reliable solution for their DC/DC & AC/DC (Off-Line) SMPS applications. The board offers a powerful and reliable solution for users, with its integrated switching regulator circuit being capable of delivering up to 40A output current with up to 11V input voltage. It is also easy to set up and use, with the main connections being the input voltage and ground connections.
