hi there
Is that possible to use a super capacitor as power supply for TPS63000/63001 and get a stable out put?
I try to power a MCU(3V, 30mA ) by using 2 super capacitor 3.3F 2.7V (connected in series) ,whose capacity should be 1,65Fand out put voltage is 5.4V
the discharge time of a capacitor is much shorter than battery ,but for my case I only need the MCU work for 1min
TPS63000/63001 has automatic Transition between Step Down and Boost Mode, input range is 1.8V-5.5V,
So I suppose that when the voltage of capacitor drops down from 5.4V to 3V , the TPS63000/63001should work as a buck regulator
when the voltage of capacitor drops down from 3 V to 1.8V the TPS63000/63001should work as a boost regulator
So I can get higher efficiency than using a single buck regulator or boost regulator
Is this idea possible?
thanks very much
