hi i need to design half bridge switch using mosfet for half bridge dc-dc converter so i need sum guide lines like what are the design considerations n requirements n gate drive circuit to drive half bridge mosfet.......... | |

The drive requirements are determined by the gate charge required to charge the gate capacitance and turn the transistor off and on at the rate you require. The gate charge value (in coulombs) is usually stated in the MOSFET data sheet. Given that, and the turn-on time you need, you can determine how much gate drive current is required to charge and discharge the capacitance (current = charge ÷ time)

I think you need something like this; http://www.irf.com/product-info/data...ata/ir2110.pdf Or one of the other half-bridge drivers. Cary | ||
