Hi,
My customer is thinking how to calculate MAX VFB at Tj=125C as follows. Is this method correct? Please let us know.
TLV62568A datasheet said VFB at Vin=5V/Tj=25C is Min:0.588V / Typ:0.6V / Max:0.612V. Also, we can find the graph of "VFB vs Tj". According this graph, Diff of VFB between Tj=25C and Tj=125C is 0.00015V. So MAX VFB @ Tj=125C is 0.612+0.00015=0.61215.
My customer wants to change inductor value from recommended 1uH to 1.5uH or 2.2uH. What problem does this cause? Please advise us.
Thanks and best regards,
M.HATTORI.
