Push-Pull Type
[Feature]
• Compared with half-bridge type, although doubled voltage is needed, meanwhile RDS(on) can be suppressed due to the use of Nch,
so a good symmetry can be achieved.
Because the current capacity is large, multi tubes driving can be made possible, and the needed parts count can be reduced.
