Push-Pull Mosfet Drivers Help Needed!!!!

Top_Gun007 · 1st December 2010, 10:55 AM

What is the best way to drive two mosfets in a push-pull configuration. The top P-ch Mosfet is connect to +30V rail and the lower N-ch Mosfet to -30V. I will be switching at 40kHz.

This is a new area for me, so any help would be a great help.

Is there a driver chip available to control both the two power mosfets (p and N)? Or must it be done in some other way?

The two Mosfets will then feed a single stage filter before delivering power to the load. Maximum output current being 15A into 1ohm.

Thank You.

Look up IR2113.
This is a high and low side driver.
It runs with two n channel mosfets.
