K32W041 API for DCDC module current?

ckielstra — Fri, 09 Feb 2024 15:30:07 GMT

We want to reduce the inrush current when waking up from sleep.

Chapter 4.2.1 of the K32W041 User Manual (UM11323) states: “The configuration of the DCDC module can be optimized to suit the load current of the application; there are settings for 10 mA, 20 mA, 40 mA and 60 mA. The default configuration is 40 mA; software APIs are available to configure the other settings.”

Can someone point me to those software APIs?

I don't understand why @Ricardo_Zamora sent me a private reply, but his short reply was that he contacted the involved team. The DCDC trimming data is provisioned in the chip factory and that the customer should not modify the load current configurations. There are no related APIs for this configuration in the SDK.

This isn't exactly an answer to the question. We don't want to modify the trimming data, but we want to select one of the available power profiles. My follow-up question was never answered.

In a new electronics design we added a small choke coil to reduce the inrush peak.
