LIBB – Recommended Power Supplies
Recommended power supplies are listed below. For best results use linear or well designed hybrid models. Most linear designs and some hybrid power supplies will be suitable for use with LIBB. While LIBB can significantly reduce switching power supply noise, the end solution will still be noiser than an average linear power supply.
For comparison of noise and ripple measurements, multiply mVpp (millivolt peak to peak) values by 0.70 to get the approximate mVrms (millivolt root mean square) value. So 10 mVpp is 7 mVrms, 5 mVpp is 3.5 mVrms and 3 mVpp is 2.1 mVrms.
For the lowest noise solution look at the Acopian A12 Series. They are well suited to large cases with high power needs. For the lowest cost linear solution look at the 3.4 or 5 Amp open frame PSUs from SL Power Electronics, Sola/Emerson, Bel Power Solutions or International Power. For smaller and lighter weight solutions look at the Daitron low noise switching power supplies.
