MAX17681AEVKITD# is an evaluation board for an efficient, synchronous buck regulator with integrated MOSFET. It offers a wide input range of 4.5V to 17V and up to a 10A maximum discharge current. The kit is ideal for a variety of general-purpose applications, such as motor control, automotive, portable devices, and LED lighting. This evaluation board is specifically designed for applications where the load current is greater than 1A and the output voltage is greater than 2.5V.

The MAX17681AEVKITD# evaluation board features high accuracy (load regulation is 0.2% typical and line regulation is 0.2% typical) and high efficiency up to 96%. The device provides an adjustable output voltage and is readily adjustable within the range of 0.5V to 17.5V. An on-board programming connector, known as the Power Management-Control (PMC) interface, is provided for controlling the external resistors. It also provides a digital logic interface with a 3-wire serial node that can be customized to meet the application needs. In addition, the board includes a user-friendly graphical user interface for control, monitoring, and logging of the MAX17681AEVKITD# features.

The MAX17681AEVKITD# evaluation board utilizes a synchronous buck topology to supply power to the load. A boost regulator is incorporated in the circuit for efficient power delivery, allowing for a higher output current than a standard buck topology. The device is uniquely designed to supply wide inputs, ranging from 4.5V to 17V, with an adjustable output voltage that can be programmed using the MAX17681AEVKITD# PMC interface.

The MAX17681AEVKITD# evaluation board is equipped with a digital programmable overload protection circuit and refers to the EEPROM memory programmed registered to provide the overload protection. The protection circuitry includes over voltage, over current, short circuit, and over temperature protection, which ensure a safe operation for different applications. The device also includes a wide slew rate control feature for noise-sensitive applications. This feature ensures the output voltage slowly ramps up and down in a controlled manner.

The MAX17681AEVKITD# evaluation board consists of a switching transformer, an output filter capacitor, a power transformer, and two sub-circuits on the main board. The switching transformer provides power to the buck regulator and the output filter capacitor smooths out any ripple in the output voltage. The power transformer also provides isolated power to the main board through a separate circuit. The two sub-circuits, located on the main board, generate additional power for the buck regulator and the output filter capacitor. The sub-circuits also provide short-circuit protection against over current and short circuit conditions.

The MAX17681AEVKITD# evaluation board is a versatile progressive buck regulator for various applications. It offers a wide input range (4.5V to 17V) and adjustable output voltage with a maximum current rating of 10A. The device is equipped with programmable current limit protection, over current protection, and over temperature protection to ensure safe and reliable operation for different applications. The MAX17681AEVKITD# evaluation board is suitable for general-purpose applications, such as motor control, automotive, portable devices, and LED lighting.
