It has two numbers, 41*4882a593Smuzhiyun the first number is the output resistor, the second number is the total 42*4882a593Smuzhiyun resistance. Therefore, the adjusted vout is equal to 43*4882a593Smuzhiyun Vout = Vout * output_resistance / total resistance. 44*4882a593Smuzhiyun $ref: /schemas/types.yaml#/definitions/uint32-array 45*4882a593Smuzhiyun minItems: 2 46*4882a593Smuzhiyun maxItems: 2 47*4882a593Smuzhiyun 48*4882a593Smuzhiyunrequired: 49*4882a593Smuzhiyun - compatible 50*4882a593Smuzhiyun - reg 51*4882a593Smuzhiyun 52*4882a593SmuzhiyunadditionalProperties: false 53*4882a593Smuzhiyun 54*4882a593Smuzhiyunexamples: 55*4882a593Smuzhiyun - | 56*4882a593Smuzhiyun i2c { 57*4882a593Smuzhiyun #address-cells = <1>; 58*4882a593Smuzhiyun #size-cells = <0>; 59*4882a593Smuzhiyun 60*4882a593Smuzhiyun max20730@10 { 61*4882a593Smuzhiyun compatible = "maxim,max20730"; 62*4882a593Smuzhiyun reg = <0x10>; 63*4882a593Smuzhiyun vout-voltage-divider = <1000 2000>; // vout would be scaled to 0.5 64*4882a593Smuzhiyun }; 65*4882a593Smuzhiyun }; 66
