The working principle of the NDM2Z-25HT-DEMO-D Evaluation Board is based on a power converter topology. The power circuit includes an input circuit, a control circuit, and an output circuit. The input circuit consists of a rectifier bridge, a filter circuit, and a voltage regulator circuit. The rectifier bridge rectifies the AC power input and the filter circuit smoothes out the ripple in the rectified power. The output circuit consists of a power switch, a power filter, and an output capacitor. The power switch switches the power on and off to regulate the output voltage. The power filter reduces the ripple in the output voltage. The output capacitor stores energy and provides a steady DC output voltage.

The control circuit of the NDM2Z-25HT-DEMO-D Evaluation Board consists of a current sense transformer, a driving circuit, a control IC, and two over-current protection circuits. The current sense transformer measures the current flowing to the output filter. The driving circuit boosts the signal voltage from the current sense transformer. The control IC receives the signal from the driving circuit and controls the power switch to regulate the output voltage. The two over-current protection circuits are used to protect the Evaluation Board from over-current and short-circuit conditions.

The NDM2Z-25HT-DEMO-D Evaluation Board is a very efficient and reliable DC/DC and AC/DC (Off-Line) SMPS suitable for a wide range of applications including automotive, communication, industrial, medical and charging. It includes many features such as a current mode topology, LED illumination, diode rectifier technology, comprehensive protection circuits, fast output short-circuit protection, UVLO and TJ high temperature protection, input surge transient protection, OTP function and thermal shutdown protection.
