Other Parts Discussed in Thread: TPS92513

Hello Team,

I'd like to ask you about VISENSE and Fsw accuracy for TPS92513.

Could you tell me the accuracy of VISENSE under the following conditions?

Condition 1

　Tj: 5 to 35 degree

　VIADJ: 0.66～0.98V

Condition 2

　Tj: 5 to 35 degree

　VIADJ: 1.10～1.61V

Also how much does the accuracy of Fsw for TPS92513?

Best Regards,

Hidetoshi Matsunami

    We do not characterize over such a small temperature range, but over the full temp range the offset of the error amplifier is +/-10mV. So the accuracy will depend on VIADJ as it will be VIADJ/6 +/-10mV. Obviously over such a restricted temperature range it will be a bit better but I couldn't give you more than a guess of about half that. The oscillator could have a tolerance of +/-20% over the full temp range although in reality it's better than that, particularly if the temp range is restricted.
