DC / DC module has been widely used in railway communications, microwave communications, industrial control, marine electronics, avionics, ground radar, fire-fighting equipment and medical equipment, teaching equipment and many other fields. Many applications require multi-output, such as SCM intelligent controller. SCM needs power supply of 5V, while the op-amp usually needs power supply of 12V. During the design of multiple outputs, there are many different points from the single output. It is necessary to consider transformer pin constraints, multi-secondary transformer design and voltage regulator circuit achievement. It is also needed to consider the load rates for light load and full load of each channel and the characteristics for cross-load regulation.
