I'm confused about DC/DC input capacitors looking at your "hardware guidelines" document and referencing that to Basic Development kit (USB dongle).
In hardware guidelines for the buck configuration says to use:
C1: 10 μF effective (output capacitor)
C2: 1 μF effective (input filter capacitor)
While the schematic shows 10uF input capacitor (on the battery side), and 1uF capacitor on the output (VBAT_LOW).
My understanding is that the comment in the brackets is wrong and you meant, considering the boost configuration has those capacitors swapped (10uF is always on the input, 1uF is on the output).
Then, looking at the schematic for the kit I have (DA14531/D2632 Basic Development Kit (USB dongle)) it has 2.2uF on VBAT_HIGH, and 10uF on VBAT_LOW, which indicates boost configuration recommended capacitors. But in this kit, by default, VBAT_HIGH gets 3.3V from the LDO and we operate in buck mode to make 1.1V-1.8V on VBAT_LOW!
Is it a mistake in the schematic?
Please elaborate on this topic.
