DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a printed circuit board arrangement comprising a printed circuit board and a power supply module to be attached to the printed circuit board, said power supply module comprising in5 connectors for receiving primary voltage and out-connectors for supplying the printed circuit board with output voltage generated from primary voltage. The invention further relates to a power supply module comprising connectors for attaching the power supply module to a printed circuit board or the like, said connectors including at least in-connectors for receiving primary voltage and out-connectors for supplying the printed circuit board with output voltage generated from primary voltage.
The invention primarily relates to producing operating voltage for printed circuit boards of telecommunications devices, but the invention can also be applied in other connections.
Besides other components, previously known solutions usually comprise components arranged on the printed circuit board for ensuring a suitable operating voltage for the printed circuit board. The component needed to produce the operating voltage for each printed circuit board is, of course, determined by the operating voltage required by the printed circuit board. In practice this means that when a printed circuit board is designed, a power supply module ensuring a proper level of operating voltage for the printed circuit board has also to be designed separately. As a result, it takes longer to design a printed circuit board, which means a higher cost level of the printed circuit board.
Moreover, previously known solutions comprise power supply components on the printed circuit board including a component, a potentiometer for instance, by means of which the output voltage of the power supply can be manually adjusted. The drawback in this previously known solution is, however, that it requires manual adjustment before the printed circuit board can be put to use.
The object of the present invention is to solve the above problem and to provide a solution by which recurrent design of almost identical power supplies can be avoided, and by which it is possible to ensure that a given power supply module attached to a printed circuit board produces a proper operating voltage for the printed circuit board from the outset, with no need for manual adjustment. This object is achieved with the printed circuit board arrangement of the invention which is characterized in that the power supply module comprises a control connector and regulator means responsive to the control connector for regulating the output voltage of the power supply module, and the printed circuit board comprises means for connecting at least one out-connector of the power supply module to the control connector through a predetermined component, whereby the output voltage of the power supply module is responsive to the electric properties of said component.
The invention is based on the idea that when the power supply module is provided with regulator means for regulating its output voltage in response to a control signal received from the printed circuit board, the power supply module is able to independently regulate its output voltage to the level required by the printed circuit board in question. Thus it is possible to provide a general-purpose power supply module which can be utilized on printed circuit boards requiring different operating voltages with no need for recurrent power supply module design or manual adjustment. Moreover, by arranging a component on the printed circuit board to allow at least one out-connector of the power supply module to be connected to its control input, a solution is achieved by which the output voltage of the power supply module depends on the electric properties of the component on the printed circuit board. In other words, by arranging components having electrically different values on printed circuit boards which require different operating voltages it is possible to utilize identical power supply modules on said printed circuit board
