IGBT gate charging calculation

I'm looking at gate driver chips right now, and I'm not sure if I'm forgetting somethign in looking at this. I want a 10kHz minimum switching frequency of the IGBT, and the IGBT I'm looking at has about (and by about I mean after VERY liberal rounding) a 1000nC gate charge at 15V. The gate driver chip has a maximum current of 1A at 15V, so I should be able to provide the charge needed by the gate in 1000ns or 1µs. Since 1µs is much smaller than the PWM period (100µs) I'm shooting for I should be good, right? Am I missing something here? Obviously I would love to have a charge time in femto- or attoseconds, but will microseconds work? Thanks!
