Other Parts Discussed in Thread: DRA829, DRA821, TDA4VM, TDA4VL

Greetings TI,

We want to implement PDN-1A power supply for our DRA829 processor complex, but are having difficult sourcing LP876411B4RQKRQ1 and was curious to the differences between the LP876411B4, B1 and B5 variants.

The data sheet and web page make no mention of the differences. Can you highlight the differences?

Thanks,

Mar

LP876411B4 : DRA829 or TDA4VM (TPS65941213-Q1 and LP876411B4-Q1 PMIC User Guide for J721E, PDN-1A)
LP876411B5 : J721S2, TDA4VE, TDA4VL or TDA4AL (TPS65941120-Q1, TPS65941421Q1 and LP876411B5Q1 PMIC User Guide for J7AEP PDN0A)
