LSF0102-Q1: power consumption computation

Sherry Liang

Part Number: LSF0102-Q1

Dear team,

Do we have power consumption tool for this device? If not, could you please tell me how to compute 3.3V-->5V power consumption?

Thanks & Best Regards,

Sherry

For practical purposes, almost all the power is consumed in the pull-up resistors. So for a single low signal, the total power dissipation is about (3.3 V)² / R₁ + (5 V)² / R₂.
