The XRP7720EVB-DEMO-1 evaluation board and its associated software package offer designers a powerful platform for evaluating the performance of the XRP7720 constant voltage/constant frequency high power factor switching power supply. It can also be used as an evaluation board for other high-power factor switching power supplies. Unlike traditionally designed using linear regulators, high power factor switching power supplies are designed using a switching regulator with a PWM feedback control circuit, which makes them highly efficient and requires minimal external components for the same output power.

The XRP7720EVB-DEMO-1 evaluation board has an onboard XRP7720 IC, which can be operated from an input voltage range of 85Vac to 264Vac. It can deliver a constant output voltage of 12V with 1% accuracy and a maximum load current of 8A. It supports active power factor correction and uses the valley correction principle, which results in improved power factor performance of up to 0.99. It has a very low standby power consumption of less than 0.6 watts.

The evaluation board also features a wide range of other features such as an adjustable soft-start circuit, a phase-shiftable output voltage, and a low output noise level. Its control circuit operates on a low-frequency clock to reduce EMI and its built-in protection features include an over-current protection circuit, over-voltage protection circuit, over-temperature protection circuit, and a short-circuit protection circuit. Furthermore, the evaluation board is RoHS compliant and UL certified.

The XRP7720EVB-DEMO-1 evaluation board comes with an easy-to-use graphical user interface software package, which is installed separately. This package allows the designer to quickly and easily adjust various parameters, such as the output voltage, power factor, and switching parameters. Also, this graphical user interface allows the designer to quickly monitor output voltage and current, as well as check for any potential errors or faults. In addition, it provides a voltage-drop compensation function that can reduce output voltage droop.

The XRP7720EVB-DEMO-1 evaluation board offers engineers a comprehensive platform to evaluate the performance of the XRP7720 high power factor switching power supply. It is a useful tool for evaluating and comparing the performance of switching power supplies, and can be used in a wide range of applications including automotive, consumer, healthcare, industrial, and military. Also, due to its efficient use of power, high power factor, and low standby power consumption, the XRP7720EVB-DEMO-1 can help designers create more energy-efficient products.
