Hello everyone,
I am currently designing a prototype with the nRF9160 chip and a 3,7V battery.
The development board, which I use as a reference, uses the ADP5360 for battery and power management.
The problem is that the ADP5360 only comes in a tiny 32-WLCSP package, which is too expensive and inconvinient for a simple prototype for evaluation.
The development board uses the following outputs:
- VSYS to supply the nRF9160 (Microcontroller)
- Buck-Regulator (1,8V) and Buck-Boost (3,3V) for other peripherals and as a GPIO reference
I am now looking for an alternative.
I need:
- 1,8V output
- 3,3V output
- An output to supply the controller at around 3,7V, but can also work with 3,3V, so it would be possible to use the same
3,3V source for the controller and peripherals - Battery charger over USB
- Battery monitoring (would be nice, not absolutely necessary)
I have looked at the ADP5350, but it has a lot of LED stuff that I don't need.
LTC3559 or LTC3558 both would provide 2 outputs but then I would have to use 3,3V to supply the controller, which is possible but not prefered.
Are there any other ICs that would meet all my criterias like the ADP5360 but in a bigger package (not BGA)?
Thank you!
