MAX3232E: Maximum charge pump cap value with Vcc=5.0V

Part Number: MAX3232E

Hi all

Would you mind if we ask MAX3232E?

How much is maximum charge pump cap value(C1 to C4) with Vcc=5.0V
Is it possible to use 1.0uF for C1 to C4?  

Kind regards,

Hirotaka Matsumoto

  • Hello Matsumoto-san,

    These values are a little larger than we typically recommend, but we can check on the impact of this and get back to you within the next few days.

    Regards,
    Max

    Matsumoto-san,

    There are no major issues of using 1.0uF caps. You will see the charging pattern change a little, but the voltage ripple and function should be same.

    Regards,

    Hao
