The strobe capacitor is rated for much more current than the 25 watt supply can put out, so the only reason to limit the current is to protect the power supply. A control Ic that has pulse by pulse current limit will protect the supply and allow max charge rate. The only other control needed is maximum voltage.

Check out Texas Instruments for ICs. The UC3526 may be what you need, see Fig. 8 in the data sheet.
