TPS61089: Shutdown current

Andrew V
Intellectual 280 points
Part Number: TPS61089

What is the total current from the input source can we expect to see when the TPS61089 is disabled?  Shutdown current into VIN pin is 1-3uA according to the Table 7.5. Are there other pins with a leakage? What is the meaning of the Quiescent current into Vout pin?

    Hi Andrew,

    Shutdwon current is different with the Quiescent current. the following table can help u understand it. In shutdown, the current flow into Vout  is depend on the dividing resistor. you can add the current inot Vin pin with the current into the output dividing resistor based on your circuit parameter.  The other pins has much smaller leakage compare to the Vin pin.  The Quiescent current into Vout pin means the current flow into the Vout pin when add a 12V voltage at Vout(set VFB=1.3V to let it no swithching)
