In both circuits sometimes, rarely it powers up immediately,which is quite perplexing.

Your 1 nF capacitor sets the oscillator frequency at about 80 kHz, which is a But if the inductor is saturating, it’ll never get there. The problem I am facing is that the voltage takes about 10s.
Post as a guest Name. Any suggestions on how to improve this? Note that this is already greater than the mA that the chip is specified to handle. As I mentioned the ebay item which I procured has similar behavior during startup.
EmbSysDev 1 1 You’re overloading it, dafasheet this is going to cut into your overall efficiency, dropping as much as 0. Laszlo 1 I am doing this on a proper pcb with a ground plane,initially i had used a DIP version on a stripboard,with slightly better results.
With a minimum input voltage of 3. Sign up using Email ddatasheet Password. They have a similar example in the ds for 15V mA,where the inductor is uH. During this time the battery voltage falls to about 1.

The inductor in this configuration does not limit the output current. I would focus on the coil. The datasheet only guarantees operation from 2V, so if your batteries are sagging below that, you’ll either need some sort of soft-start circuit or some extra cells to stay above the minimum operating voltage. Hello all, I have this circuit which will take an input daatasheet.
