LM3410 Constant Current boost with a inductiv load

Other Parts Discussed in Thread: LM3410

Hi,

I use the LM3410X Constant Current Boost, to create a constant current of 225 mA (Rsense=0.83 ohm)

Inductor 10 uH/1A, test circuit as in datasheets

With an resistor as load the start-up, regulation etc. are controlled perfect.

But it is intended to be use driving a solenoid 27ohm/70mH, with the solenoid the current is no longer in phase with voltage. The result is LM3410 adjust the duty cycle for every cycle, until the current reach 2.3A (current limit)

Can I do something to limit the current, some smart tricks in the feedback part ? I have 100 ohm in series with FB pin.

Thanks in advance
