AM2634: Suitable PMIC or multi-Channel DCDC?

AnBer

Part Number: AM2634
Other Parts Discussed in Thread: TPS62826, TPS54334, TPS62442-Q1

Team,

I have already checked the discrete power tree implemented in theTMDSCNCD263 Control card (TPS54334 for 3.3V, TPS62826 for 1.2V, 1.8V seems to be internally generated by the AM263x).

Would the TPS62442-Q1 (Dual-channel DCDC) be suited to power the 3.3V and 1.2V power rails?

Thanks in advance,

A.

    Hi 

    Apologies for the Delay, this thread has been dropped out and lost. Is your query resolved?

    If not, I have checked the different power consumptions in Am263 (Datasheet):

    Here, we have VDDAR (1.2V) and VDD (1.2V) need maximum 2.5A. And VDDS (3.3V) need maximum 200 mA.

    For the  TPS62442-Q1 (Dual-channel DCDC), you have shared, the current and voltage specs are as below (datasheet):

    Input and Output Voltage Ranges:

    Here you can consider the input, output min and max voltages. TPS62826  also has input voltage range of 2.4-V-5.5-V. Hence, 6V max input should be okay.

    Here, the 3A and 1A combination can be used for 1.2V and 3.3V power rails.

    So this TPS62442-Q1 should be suitable for the AM263.

    Please share us your inputs as well. Are these current requirements suitable for you?

    Thanks & Regards
