Onur,
DRV2605L has VSSOP package, you could consider this part.
Regarding the PWM modulation frequency, it would depend on the actuator you're driving. Basically the actuators only "see" the average of the PWM signal, so if PWM frequency is too low, the actuator could be fluctuating around the average value. By increasing the PWM frequency the average "variation" is reduced. Different motors have different time constants. Specifically talking about LRAs, you need a PWM frequency high enough for LRA resonance frequency to be "seen" as stable as possible, same as motors.
You can try with DRV2605 PWM frequency ~20kHz.
