I want to design a dc-dc boost converter and manage power (MPPT) for an ultra-low power fuel which contains input voltage < 1 V and input current < 500 uA. if I choose simple boost converter, I will have problem with inductor design because low input current (about 500 uA) will cause extremely high inductor.

Here is the formula for calculating inductor for simple boost converter [L= (VinD)/(fs0.3*iL)]

I need to choose high freq and high L that means an inductor with more than 10 mH inductance and work in 5 MHz freq. (we don't have inductance in this spec) what should I do for power managing of this ultra-low fuel?
