On 137kHz the
TC4426 works fine. On 500kHz it works pretty good when driving 2 single
IRFP350's.
But to be on the save side I prefer to have 2 x 2 IRFP350's in parallel
and that is too (capacitance) much for a TC4426 at 500kHz.
The IR2110 has an output current of 2.5A while it is only 1.5A  for
the TC4426.

To my
own surprise the local electronic shop sells them of the shelf (abt 4
Euro).
