> transformers windings in vs windings out

Transformers only apply to AC, where there is a fluctuating magnetic field.

A transformer in a DC circuit is just a physically large (very low resistance) resistor.

The standard practice to convert DC voltage (at least for these voltages) would be a buck converter, which is an active circuit. [1]
