Hi —
I'm developing the power management system for a new concept of mine.
I'm looking for the easiest way to regulate 3.3V from a battery and charge it using an MPPT. I'll probably use gallium arsenide triple-junction cells, which will have a power consumption of under 20ma at 3.3V. It needs regulated voltage for the atmega 328p au chip and other IC's. The cells have an open-circuit voltage of 2.62V and a max power current of 14.6 mA.
I see that the SPV1040 might integrate MPPT circuits. I have to charge a 3.7V cell (approximately 500Ma).
The thing is, I have a pretty rudimentary understanding of charging circuits. Is there any efficient MPPT/Battery charge controller IC's on the market or easy to design and existing devices? I know that form factor is important since this will be going in a pretty small space.
I'd like to hear your thoughts. And if you'd like to virtually collaborate, let me know and we can get connected.
Thanks.
