There are a number of situations where one needs a burst of power; for example, when using an iridium or GSM modem, when flashing a powerful led, etc. A good solution then can be to use some circuitry to i) charge some supercaps ii) perform the operation that uses a lot of current when the supercaps are full, combining power taken from the supercaps and from the battery. This is for example the method used by the Artemis Global Tracker https://www.sparkfun.com/products/18712 , which has a LTC3225 and in-rush current limit, in order to provide bursts of power to the iridium modem.
My question is: would it be possible to provide such a functionality also as a standalone breakout, as this is a need that arises quite often, also in other applications? For example, I am having issues with the Qwiic Cellular Notecarrier - Blues Wireless https://www.sparkfun.com/products/17114 taking too much current, which browns out my MCU, when batteries are not completely full. Having a breakout similar to the AGT LTC3225 would help solve this problem, as I could add it to my design, and help alleviate the worst of the power surge!
