What is the maximum input voltage for VLDO34, in MC32PF3000A2EP

[logeshs]

Hi,

We are using PMIC MC32PF3000A2EP in our design with MCIMX7D3EVK10SD.

1: What is the maximum input voltage for VLDO34? There are two different specs available in datasheet. At page 25, it shows 2.8V to 3.6V. In Figure 5 Power map, VLDO4 input is connected to VIN and says 4.5V(Typ).

Please let us know which one should I refer.

Thanks

Hello,

  According to Table 3 (Absolute maximum voltage ratings) of the PMIC Datasheet (PF3000,
Rev. 9.0, 8/2017 ), voltage range for VLDO34IN  is -0.3 to 3.6 (V)

Have a great day,
Yuri

Hello Yuri

When I look at the i.MX7Sabre EVB schematic, VLDO34IN is supplied 3.7V and when I look at the PF3000 EVB, VLDO34IN is supplied with Vin which is also 4.4V. Are you sure that the datasheet is correct?

Many thanks for your efforts.
