I have a basic doubt. Suppose I am using TPS78601KTTRG3 to generate an output of 3.3 V and the voltage at input pin number 2 is connected to a battery of range 4.2 V (Max, when full charge) to 2.8 V (Min). Also 3.3 V is connected to many active ICs whose total current will be 435 mA. My doubt to you is that will the input current (current through pin number 2) be always greater than output current,i.e., 435 mA), when the battery discharges slowly from 4.2 V to 2.8 V.
Also note that my EN pin is connected to IN pin. So how much will be the EN current be, when the battery discharges slowly from 4.2 V to 2.8 V.
