TPS62A03: Inductance

Shuhei Goto
Expert 4910 points
Part Number: TPS62A03

Tool/software:

Hi team,

In the datasheet, 1uF or 0.47uF are recommended as output inductor.
Is there any performance difference between these two value?

Best regards,
Goto

    Hi Goto,

    With a smaller inductor you can get better load transient response and better efficiency at higher loads as it will have a lower DCR compared to a larger inductor. With a larger inductor you will get a smaller output ripple when compared to a smaller inductor.
