TPS730: TPS730

Part Number: TPS730


    I have one more query regarding the Feed back pin current testing.In TPS730 datasheet the specification is below.

For testing this, Need to force 1.8V from ATE to FB pin and check the current ?

What should be the status of output voltage that time? I feel the output wont be stable.Is it required to monitor the output voltage during this test?

Please suggest the steps to validate this parameter.

  • Hi Anuraj,

    Usually a unity gain will be set for Ifb leakage measurement. With unity gain, Vout is shorted to Vfb. Since the leakage current is very small, a resistor will be put between Vout and Vfb and a voltage across the resistor will be measured. The leakage Ifb = Vdiff / R.
