Hi,
I'm looking for an appropriate mosfet driver for my setup.
I'm working on a class E driver, switching at 13.56MHz. The power mosfet that I'm using is STB13NM60N from STMicroelectronics.
I'm currently driving the mosfet with the EL7104 mosfet driver from Intersil, output straight connected to the gate, Vdd of driver decoupled with 10microFarad tantalum cap. Results are poor at this moment. At 1MHz it works fine, but at higher frequencies, it becomes inverted and more of a sinusoidal wave; also the mosfet isn't switching on and off properly (sometimes it doesn't switch off properly, and it just draws a lot of current from the power supply).
Should the EL7104 driver be able to work up to 13.56MHz?
Any suggestions, ideas to get it working?
Or anyone know of a driver that works well at high frequencies?
(I've found for example the DRF1200 from Microsemi, but unfortunately the local supplier where I need to order my components, doesn't offer it for sale).
thanks
