About PF3000A4 SW2 output (3.3V) for i.MX6SL.

[keitanagashima]

Dear All,

MC32PF3000A4EP

Programming Options : 4 (i.MX 6 Series with DDR3)

In above ”A4” programming, SW2 output 3.3V (+-6%).

But, the VDD_HIGH, NVCC33_IO: 2.8Vmin - 3.3Vmax were defined by i.MX6SL.

Is it possible to use the MC32PF3000A4EP for i.MX6SL?

Best Regards,

Keita

Hello,

  App note AN5113 (Powering an i.MX 6SL Based System Using

the PF3000 PMIC) provides recommended configuration in Table 2 (PF3000 + i.MX 6SL

Power Tree), assuming LPDDR2 (preprogrammed A5 configuration).

  Nevertheless, considering the A4 case regarding 3.3V, note,

maximum GPIO and VDD_HIGH_IN supply voltage (Absolute Maximum Ratings) is 3.6V ; this

allows to decrease the SW2 output below 3.3V as soon as possible after boot for reliable

operation.

Have a great day,
Yuri

OK. Thank you.

But, the target is DDR3(1.5V).

Hi Keita,

Yes it is officially supported, see this https://www.nxp.com/webapp/search.partparamdetail.framework?PART_NUMBER=MC32PF3000A4EP

Dear Michal,

Thank you for your prompt reply.

SW2 output 3.3V (+-6%) : Max 3.498V!

The voltage outs of operating range in i.MX6SL.

Is it possible to guarantee the voltage (3.498V) on VDD_HIGH, NVCC33_IO of i.MX6SL?

Best Regards,

Keita
