Original question:

LM5157: LM5157

LM5157: Output noise data request

Part Number: LM5157

Hi team,

This is FAE Jayden, My customer is evaluating LM5157 with MPS's part.

Do we have any output 1/f noise, output voltage ripple or PSRR data that can share with ZTE to fight with MPS? Thanks.

Brs

    Hello Naveen Jayden,
    Thanks for reaching out to us via e2e.

    As far as I am aware, the ripple on the input- and output side depends on the external circuitry around the controller, for example the size and quality (ESR, ESL) of the input and output capacitors, inductor, switching frequency, etc.
    So, there is no such number that could be directly related to the LM5157 controller itself. It always depends on the whole application.

    Best regards,
    Harry
