Dear Oracle,
I'm designing a boost converter where the input is a current limited (~500mA) voltage source that varies from 3.5V to 6V. The output (load) varies from 7V to 9V. I intend to drive a MOSFET, IRF8707PBF [1] from IR, with a 250kHz PWM control signal via Maxim's driver IC MAX4420 [2].
Do you see any unforeseen mis-happenings in your crystal ball, if I chose to mate the two devices at the given frequency and voltages?
Other comments/questions on driving MOSFET's or on the boost topology in general are welcomed.
