Enable TPS65217

Maxwell Weru

I have a design that involves using TPS65217x but I see from the datasheet, page 67, all LDOs and DCDC outputs are disabled by default. I need at least one LDO to be powered up host. Please advice

    Maxwell,

    The register default values are referring to the instant the part turns on, before the sequencer runs. Depending on the part you have (A, B, C or D) you LDOs and DCDCs are enabled in a particular order and set to a particular voltage. See page 4 for sequencing and voltages for each device.
