The NMH1205S operates by converting the input DC voltage into a high-frequency AC signal, which is then passed through an isolation transformer. The secondary winding of the transformer outputs a different AC voltage, which is then rectified and filtered to produce the desired DC output voltage. The isolation transformer provides galvanic isolation, which prevents any DC current from flowing between the input and output circuits. This isolation helps to protect sensitive electronic components from damage caused by voltage surges or ground loops.

This DC-DC converter is typically used in applications where safety is critical, such as medical equipment and industrial control systems. It is also suitable for use in battery-powered equipment, where it can provide a stable and regulated output voltage from a fluctuating battery voltage. The NMH1205S is designed for surface mount technology (SMT) assembly on printed circuit boards (PCBs) and operates within a specified temperature range to ensure reliable performance.
