How to Configure Power of DA14531 DK PRO
On DA14531 DK PRO, users can:
●
Set DA14531 SoC on Buck, Boost, or Bypass mode (applied to J4 on PRO-MB),
●
Provide four different voltage rails to DA14531 SoC, that is, 1.1 V, 1.8 V, 3.0 V, and 3.3 V
(default) (applied on J5 on PRO-MB),
Jumper settings of J9 enables the current sensing circuit,
. Jumpers are applied by default.
On DA14531 PRO DBs (WLCSP17 and FCGQFN24), users must set SW1 to buck position
permanently. The power circuit consisting of U2 and SW1 on PRO-DBs is not needed.
