TPS659x0 Errata - DC2DC efficinecy (#21)

Yair Hougui
Expert 5615 points

Hi, 

A customer of mine reviewed the Errata sheet (http://focus.ti.com/lit/er/swcz001b/swcz001b.pdf ) and the following questions came up.

 

1) Are there any efficiency graphs to backup this information?

2) The workaround suggests to use the DC-to-DC converter with minimum capacity. This can be done at system boot and the question is what happens when power demand increases due to system needs, Will the dc-to-dc be limited?

3) is there a need to reconfigure the converter to its hig power settings in such a case?

 

Thanks,

Yair

    Hi,

    We dont have any efficiency curves. If he workaround is implemented then the DCDC will function normal. Please refer to the following post -

    Hope this helps.
