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.
Power Trends (a TI subsidary) makes excellent DC/DC converters (I blow about 10 homemade DC/DC converters (not my design) a month and have yet to blow a PT6302 (24 to 5) with several 1000s i8nstalled. The PT converters evan are cheaper than the homemade ones. Erik I fully agree; the Power Trends products are excellent, and can take quite an electrical beating without damage. Since the OP specified his current requirements are small, the PT5101 might be even more appropriate. Among other things, the smaller size and simplicity of the 3-pin (read: 7805 pin-compatible) interface are nice. --Sasha Jevtic |
