SiC45x

A library to talk to the SiC45x series buck converters using I2C (Wire). It provides implementations for almost all features of the SiC45x series buck converters as described in the datasheet. It is designed to be used with the Arduino Wire library.

Usage

Usag is straigt forward. A simple example looks as follows

#include "SiC45x.h"

SiC45x sic45x(0x0F);

void setup() {
  Serial.begin(115200);

  sic45x.begin();

  sic45x.setFrequencySwitch(1000);
  sic45x.setInterleave(SIC45X_INTERLEAVE_MODE_MASTER);
  sic45x.setVoutCommand(.5);

  sic45x.printStatusWord();

  sic45x.setOperation(
    SIC45X_OPERATION_ON_OFF_ENABLED
    | SIC45X_OPERATION_OFF_B_IMMEDIATE
    | SIC45X_OPERATION_MARGIN_COMMAND
    | SIC45X_OPERATION_MRGNFLT_FOLLOW
  );
}

void loop() {
  Serial.print(F("I_OUT: "))
  Serial.print(sic45x.getReadIout());
  Serial.println(F("A"))

  delay(1000);
}

A more complete setup can be found in the example sketch.

Regenerate API

SiC45x.h and SiC45x.cpp are generated from /extras/generateApi.js. The structure of the library can be updated by making changes to that file and rerunning the generation:
