TPSM846C24DEVM-007: Output capacitor in parallel

Part Number: TPSM846C24DEVM-007
Other Parts Discussed in Thread: TPSM846C24

Tool/software:

Hi team,

The TPSM846C24 recommends 4x47uF and 2x470uF output capacitors.

In the parallel EVM, they are 2x47uF and 2x470uF, respectively.

The number of ceramic capacitors is less than recommended.

Is it not necessary to use 4x47uF when using in parallel?

  • Hi Hirotsugu,

    The minimum capacitance is per output, the 2PH EVM shares the same output and therefore together meets the recommended COUT = 4x47uF and 2x470uF by implementing COUT(total) = 4x47uF and 4x470uF.

    Regards,

    Eileen
