Small DC to DC Converter Modules

HOME
  Used to generate supplememtary voltages on circuit boards.

Reverse engineered circuit diagram of two different DC to DC converters of the type used on old 10bT LAN cards.

Circuit Diagram aka Schematic reverse engineered from circuit board

They are both fairly identical in operation and specification. In fact they are pin compatible and interchangable.
