Part Number: TPS659037

If the Cin and Cload ( capacitive load driving capability)vlaues are not available , what reasonable values can be assumed?

I need to know the Cin and Cload values for each pin of TPS65903x( where ever applicable)

    Bhargav,

    Hi, thanks for reaching out to us on E2E.

    The recommended capacitor values for the TPS659037 can be found in the spec table of the datasheet, with descriptions in section 6.2.2: www.ti.com/.../tps659037.pdf

    In summary,
    LDOx_IN pins: 2.2uF typical
    LDOx_OUT pins: 2.2uF typical
    SMPSx_IN pins: 4.7uF typical
    SMPSx_OUT pins: 47uF typical
    VBG pin: 0.1 uF typical
    VCC1 pin: 10uF typical
    OSC decoupling caps: 10pF (per side of the crystal)

    Please let me know if this is what you are looking for.

    Thanks,
    Nastasha
