LM5576: Minimum operating current

Ryo Akashi

Part Number: LM5576

Hello experts,

Does LM5576 have minimum operating current?

It depends on inductor ripple current?

Thanks and best regards,

Hello Ryo,

There is no limitation on the minimum operating current. But please connect PRE to SW if the application requires to operate at light load.

Please close the thread if you think my response answered your question. Thanks!
