Other Parts Discussed in Thread: TPS55340
I'm using TPS55340-Q1 in SEPIC topology.
TPS55340-Q1 has 2.9V minimum input voltage. I'm going to use some bulk capacitance (polymer or maybe EDLC) to withstand input voltage dropout.
So it would be very useful if this SMPS could provide output voltage with Vin less than 2.9 volts (to use energy stored in bulk capacitors).
Please see attached schamatic.
Whether the power supply will continue to work correctly if the input voltage falls below 2.9? Of course untill switch current does not exceed maximum value.
Thank you in advance.
