I replaced L1704 with a TDK VLF3012AT @ 2.2uH (data sheet: http://www.tdk.co.jp/tefe02/e531_vlf3012a.pdf) and repeated the experiments. With this new part the efficiency of the conversion jumped to 80% :-) Cheers, -- Aaron _______________________________________________ hardware mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/hardware
