I got a supercap boot converter circuit.
Supercap voltage is 2.6V output 5V.
The problem is when the input falls below 1.8V the Enable is switched off and the Boost converter is disabled. So most of the energy stored in the supercap is wasted. Any sugestions to solve this?
Attached a scope picture with the described behaviour.
Green output voltage
Yellow supercap voltage. EN is directly connected to Vin.
Thanks.
