  • LM2623: Please check if we have any replacement that is cost effective

    Part Number: LM2623 I am finding a replacement material for AP3015KTR-G1(Diodes), witch price is 1.9USD, so aggresive. Cusotmer need input voltage is less than 1.5V and the output voltage is greater than 12V. Do we have any recommendations? thanks.
