Hello,
I have made a -5V inverter design with LM43601PWPR IC. But in the design, 27uH inductor and 150uF capacitor have a big footprint. I have successfully got -5V but this design conquers too much space on my PCB. How can I select the smaller inductor and capacitor components?
Or do you refer any other design converting 7.4V to -5V with 0.5A with less than 300mm2 place on the board and less components? But main IC should be SOIC or other related packages, not as QFN type.
Thank you
