The military TF34 is one, and the early CF34's too: Single-stage fan driven by a 4-stage LP turbine, and a 14-stage HP compressor and 2-stage HP turbine core. Said core is a scaled-up version of the T64 helo & turboprop engine.
That makes sense -- evolving a free-turbine turboshaft or turboprop to a fan on the LP stage. Thanks.
