One of my customer has selected TPS55065-Q1 for his project and he has certain query about the Iq current of the IC at the current levels that he requires.
1. In our system the load current will goes to 120uA when the micro goes to sleep mode. We would like to know if the load current goes to 120micro amp then what will be the input current (Dark current/Quiescent Current) 2. Low power mode if I am not controlling then how the chip will behavior. As per my understanding the chip will goes to low power mode at Buck if the load current is low ie <1mA automaticaly.Is this correct or I need to control CLP pin?
The the device will be in LPM and the quiescent current will decrease at light load. I measured a 75uA increase over the baseline "no load" quiescent current when a 120uA load is added to Vout. The device will transition to LPM automatically as the load current decreases, if the CLP input is low. It will not transition to LPM, if CLP is high.
