Hello , i have the ic spv1040 , and I have one problem in my design : The integrated circuit supports from datasheet around 5.5V input , but my solar panel have around 6.5V (Maximum power 1W) in full sunny day .

[APand.12]

How can i manage this ? Does the circuit sustain voltages in range of 5.5-6.5 ? I need an extra electronic circuit for ic to work properly ?
