Works ok but minimum input needs to be about 12v not 10. Was only able to test between 10-30v input and 12-50v out and up to about 200w. Efficiency was generally between 87 and 93% over this range.
While the smds board appears good, the placement of some the through hole components was a bit sloppy. Most notably the heat sink insulator on one of the power transistors was on upside-down so that transistor metal made contact with the heat sink.
