This is a design circuit for basic schematic of the LM25037 dual gate driver switching the gates of two FETs independently. This is the figure of the circuit;
Switching two independent FETs from a dual gate drive controller typically allows the designer to select low RDSON FETs with a higher gate charge. Higher gate-charge FETs tend to be less expensive than their lower gate-charge counterparts. The two FETs selected to be switched independently are the SiR468DP. As previously mentioned, driving two FETs in parallel produces a 50% reduction in RDSON. Switching FETs independently, however, no longer yields the 50% reduction in RDSON but transitional losses are reduced.
