  • RE: TPSM846C23: Select parts for provide power for DDR3/4 DRAM with PMBUS control

    Resolved
    Gerald Millar I am not aware of a PMBus enabled termination LDO, but since the VTT and VTT_REF specification is 1/2 of VDDQ, a Tracking LDO without PMBus would generally be a valid, or even preferred solution to a programmable one. You can recommend…
