AWRL6432: 1.8V and 1.2V power solution suggestion.

Part Number: AWRL6432
Other Parts Discussed in Thread: TPS746-Q1, TPS745-Q1

Hi team,

I have a question here that since my customer would like to use LDO to provide the power for 1.8V and 1.2V. I recommended they use TPS745-Q1 and TPS746-Q1 which has lower cost as AWRL6432 1.8V and 1.2V companion power.

However we notice that the power solution need meet noise and ripple spec to follow AWRL6432 datasheet. I have not idea that how to judge those spec. would you please help me to check TPS745-Q1 and TPS746-Q1 are OK to use at AWRL6432? or you have recommendation power solution here. thanks!



  • Hi Jimmy,

                What is the target applicaiton? Is it automotive or industrial?

    This will define the typical power architecture of the system as there may be a wide VIN, pre-regulation stager requirement. 

    You can take a look at the belwo LDO's also.

    TPS78418QWDRBRQ1(1.8V and 1.2V)


    If the pre-regulator is needed then in that case a pre-regulator integrated dc-dc woudl be better choice, as LDO's would have inefficiency.
