While designing a Li-Ion powered device I’m searching for a battery charger IC with two main functions:
- use the input power (in USB range) to either charge the Li-Ion (up to 500mA) or power the load (up to 500mA) or both (depending on the load)
- power to the load shall be buck/boosted to 3.3V independent from input voltage or Li-Ion voltage
The MP2632 is almost fulfilling these requests, but its output is fixed at 5V.
Is such a device available?
Thanks!
