Hello guys,
One of my customers is considering using TPS40210 for their new products. Also they want to use conductive polymer aluminum solid electrolytic capacitors,
PCR1K390MCL1GS (Nichicon, 39uF, ESR=35mohm) as the output capacitor of TPS40210.
PCR1K390MCL1GS
https://www.nichicon.co.jp/english/products/pdfs/e-pcr.pdf
According to their calculation result by equation (46) in datasheet , the output capacitor ESR must be less than 115mohm. So PCR1K390MCL1GS is no problem to use because the capacitor ESR(35mohm) is less than 115mohm.
Can this CONDUCTIVE POLYMER ALUMINUM SOLID ELECTROLYTIC CAPACITORS be used for output capacitor of TPS40210 with no problem?
If you find any concern, could you tell me your comment?
Your reply would be much appreciated.
Best regards,
Kazuya.
