A very simple supercapacitor charger electronic project can be designed using the LTC3625 IC designed by Linear technology to charge two supercapacitors in series to a fixed output voltage (4.8V/5.3V or 4V/4.5V selectable) from a 2.7V to 5.5V input supply. Automatic cell balancing prevents overvoltage damage to either supercapacitor while maximizing charge rate without using any balancing resistors .
This electronic circuit project presented in this circuit diagram has high efficiency, high charging current, low quiescent current and require low minimum external parts
A very simple high efficiency power supply circuit can be designed using the NCP3337 high performance low dropout regulator, manufactured by ON Semiconductor.
With accuracy of 0.9% over line and load and ultra−low quiescent current and noise it encompasses all of the necessary features required by consumer electronics.
The NCP3337 also comes equipped with sense and noise reduction pins to increase the overall
utility of the device.
