TPS92510: Peak to Peak inductor current

Takao Yamamoto5

Part Number: TPS92510

Dear all,

At recommended operating conditions, you mentioned that 'Peak to Peak Inductor current Min.=150mA'.

What is the reason why you recommend this value?

If I operate out of this value, what is concerned?

Best regards,

    Hello Takao,

    The minimum recommendation of 150mA peak-to-peak is just to ensure there is enough slope/signal for the current mode control to operate well. If you make it too low you can lose some accuracy and if low enough you may get oscillations.

    Regards,
