Hi,
I am currently looking for a buck-boost battery charger IC for a battery backup system. The system is DC powered that is supplying 5V/5A to a 5V power rail and a 3.3V power rail. The max power demand for the system is 5V/4.8A and 3.3V/2A.
The requirements for the buck-boost battery charger IC are:
- Being able to boost off the battery 5/1.2A and 3.3V/2A as the power demand increases.
- Charge the battery when the power supply increase is not needed
- Provide power to the system when the 5V/5A power input is cutoff using the battery
- Easily integrable into an existing design, so a reference design/ design advice is needed as well.
Thank you.
