so here is a P-Q curve for the MCP1200
nominal output / input = 45 / 80 Watts; at 12VDC
so what is the price ?
think . . . . 3X the capability, . . . . 3X the price
for one pays for performance, given no economies of scale
note that this product is not now being offered,
as I suspect there are perhaps 4 actual purchasers lurking about
