The P048F048T24AL-CB is an excellent solution for applications requiring high performance DC/DC and AC/DC (off-line) switch mode power supplies (SMPS). This evaluation board provides an efficient and robust method to test, evaluate and develop SMPS products. This board is specifically designed to test DC/DC and AC/DC (off-line) switch mode power supplies, and features numerous design considerations to aid performance, including improved switch-mode control, ripple reduction, improved transient response, and increased efficiency.

The board utilizes differential current sense for accurate current sensing. The differential current sense approach offers a higher accuracy level compared to traditional sense methods. It also allows for the possibility of the accurate adjustment of current sense resistor values. This control permits output current to be adjusted accurately and easily, without the need to rewire the board. This design consideration improves accuracy and reduces tuning times.

The P048F048T24AL-CB evaluation board also provides a built-in voltage regulation function. This allows the user to maintain a desired output voltage over varying input voltage conditions. The voltage regulator consists of an adjustable bias voltage generator, two voltage reference components, and an op-amp. The bias voltage generator and voltage references set the output voltage, which can be adjusted using the trim pot. The op-amp maintains the voltage based on the feedback from the voltage reference components. This voltage regulation is very accurate and reliable, resulting in less oscillation and high stability of output voltage.

The P048F048T24AL-CB also provides a comprehensive EMI-reduction feature. This feature minimizes noise generation on the power plane, thus ensuring improved EMI compliance. The EMI feature uses an array of noise-suppressing capacitors connected to the power plane ground potential to reduce common-mode and differential-mode noise.

In addition, the board features comprehensive protection functions, such as overvoltage and overload protection. These features ensure safe operation of the switch mode power supply and protect the device from short-circuit and over-current conditions. The board also provides protection from over-voltage conditions, such as over-temperature, over-current and over-voltage protection.

The P048F048T24AL-CB evaluation board provides a comprehensive solution for testing and evaluating DC/DC and AC/DC (off-line) switch mode power supplies. This board features numerous design considerations to ensure efficient operation and reliable performance, such as differential current sense, voltage regulation feature, and EMI-reduction feature. The board also provides comprehensive protection functions for safe operation, making it an ideal solution for testing and evaluating switch mode power supplies.
