I need a way on my PCB to step up 5V to 12V (with currents up to 2A). I've been looking at the XL6019 IC and tried to copy the design from the sample circuit of the datasheet:
I'm currently stuck at the L1 inductor since I'm unable to find a 47uH (reasonably priced) inductor which is rated for 5A. Furthermore if I have a look at the simple boards from AliExpress out there I'm doubting that the inductor they use can handle anywhere near 5A.
How important is this current rating? Or do you maybe know other low cost ICs which could handle 12V with 2A? Thanks in advance!
