#104190 - DC to DC converter |
I have an 89C52 board that collects data from two CNC machines , stores in external external memory with date and time stamp, and hands over to a PC under a protcol. RS232 connections to two CNC machines are isolated using 4N25. Separate power supply (+12V,-12V for RS232 side - 1488,1489 drivers/receivers are used) is provided for each section, using multple winding transformer and separate rectifiers and regulators. Current requirement may be in the order of 100-150mA.
Now this board has to be made to work on 24V DC power supply. I need to derive three independent power supplies from this single DC source. Search on the forum for DC to DC converter did not yield relevant material. Any suggestions on how to do this? Any recommendations on DC to DC converters? Maxim? |
