It15 supports boost and auto bypass mode that depends on the difference between the16 input and output voltage. If the input is lower than the output, mode will17 transform to boost mode. Otherwise, turn on bypass switch to enter bypass mode.18 19 Datasheet is available at20 https://www.richtek.com/assets/product_file/RT4803/DS4803-03.pdf21 https://www.richtek.com/assets/product_file/RT4803A/DS4803A-06.pdf22 23allOf:24 - $ref: regulator.yaml#25 26properties:27 compatible:28 enum:29 - richtek,rt480330 31 reg:32 maxItems: 133 34 richtek,vsel-active-high:35 type: boolean36 description: Specify the VSEL register group is using when system is active37 38 regulator-allowed-modes:39 description: |40 Available operating mode41 1: Auto PFM/PWM42 2: Force PWM43 items:44 enum: [1, 2]45 46required:47 - compatible48 - reg49 50unevaluatedProperties: false51 52examples:53 - |54 i2c {55 #address-cells = <1>;56 #size-cells = <0>;57 58 regulator@75 {59 compatible = "richtek,rt4803";60 reg = <0x75>;61 richtek,vsel-active-high;62 regulator-name = "rt4803-regulator";63 regulator-min-microvolt = <2850000>;64 regulator-max-microvolt = <4400000>;65 regulator-allowed-modes = <1 2>;66 regulator-always-on;67 };68 };69
