TLV62569: Schematic Review

Kuan Wei Chen (Kevin Chen)

Part Number: TLV62569

Dear Team,

Can you double check the schematic?

If there is any concern please let me know.

Besides, how to calculate the Iout OCP base on high side current OCP spec?

The Iout is a constant value but high side current is triangular here, so I am not sure 3A here mean Iout=?

    Hi Kevin,

    the values of your feed forward capacitors are way off. I would recommend 6.8 to 10pF instead of 100nF.

    The OCP value in the datasheet is the minimum current allowed through the highside FET.
    When switching, the peak inductor current must be below this threshold to ensure proper operation.
