Seems to deliver stable 5V (approx) power under a wide range of input conditions. However, the efficiency is not particularly high at low currents, as would be expected. Attached is a table of efficiency calculations using my non-calibrated equipment. No load current is 5mA which is a bit high for my liking. John from Ontario, Canada

  • John-Glammis Somehow the efficiency table was not attached. Here is part of it in plain text.Please note that my instruments are not calibrated.Input Output Input power Output power, EfficiencyV ma V ma mW mW 570 4.73 1010 6840 4777 7025 300 4.80 1010 7500 4848 6512 800 4.69 1490 9600 6988 7325 420 4.69 1490 10500 6988 67
