The LMR61428XMMEVM/NOPB is an evaluation board designed for efficient off-line DC/DC and AC/DC SMPS applications. It\'s an easy-to-use board with simple and intuitive connections and includes all the necessary components to power DC/DC converters, isolated regulators, and other SMPS topologies from a single 5 V or 12 V input. The board also features a wide output voltage range and is capable of delivering up to 25 watts with an efficiency >70%.

The circuit of the board consists of a synchronous buck PWM controller from Texas Instruments, the LMR61428XMME. This controller provides very high efficiency with low current ripple, allowing for wide bandwidth, and reliable operation even in heavily loaded conditions. The output voltage is adjustable from 0.80 to 17V and the board can deliver up to 25W of power. The board is also equipped with an easy to use interface to configure the board\'s operation and test the performance of the system.

The board\'s integrated PWM controller provides comprehensive protection functions such as under voltage lockout, over voltage protection, current limit and thermal shutdown to protect the system from potential operational hazards. It also has a wide operating temperature range from -40°C to + 125°C. The NOPB also features up to 2.5% accuracy and is capable of providing up to 400kHz operating frequency.

The LMR61428XMMEVM/NOPB can be used in a variety of applications, including powering DC motors, fans, pumps, lights, and air conditioning systems. It is also suitable for non isolated converter applications such as LEDs, LCD displays, and stepping motors. It can also be used in AC/DC applications such as DC/DC power supplies and power supplies for industrial and communications applications. The board also features a comprehensive set of features, such as selectable soft start, selectable burst mode operation, programmable protection features, and an option to disable the control loop.

The board\'s PWM controller is highly programmable and allows for a wide range of application requirements to be met. It offers users the ability to tune the output voltage, adjust the frequency and duty cycle, as well as set the current limit. The PWM controller also features a built-in phase-shift modulator for enhanced stability and efficient operation in different operating frequencies.

The LMR61428XMMEVM/NOPB is a very reliable and efficient board that offers simple and intuitive connections, extended capabilities, and a wide range of applications. It\'s a great way to quickly and easily explore DC/DC and AC/DC SMPS topologies and configurations with a single board. The board is easy to use and offers great performance in a cost-effective package.
