Follow on question, Once everything has powered-up, can I reduce the PF0100 SW1A/B output to 1.2V and bypass the internal LDO_ARM in the iMX6SL for normal operation? Same question for the PF0100 SW1C output for VDD_SOC_IN and VDD_PU_IN.</P></BODY></HTML> Mon, 21 Apr 2014 19:14:24 GMT https://community.nxp.com/t5/i-MX-Processors/PF0100-SW1A-B-output-voltage/m-p/300781#M37791 muthunagarajan 2014-04-21T19:14:24Z Re: PF0100 SW1A/B output voltage https://community.nxp.com/t5/i-MX-Processors/PF0100-SW1A-B-output-voltage/m-p/300782#M37792 <HTML><HEAD></HEAD><BODY><P>Hello,</P><P></P><P>Thank you for your post, however please consider moving it to the right community place (e.g. <A _jive_internal="true" class="jivecontainerTT-hover-container jive-link-community-small" data-containerid="1" data-containertype="14" data-objectid="2004" data-objecttype="14" href="https://community.nxp.com/community/imx">i.MX Community</A> ) to get it visible for active members.</P><P>For details please see general advice <A _jive_internal="true" data-containerid="2001" data-containertype="14" data-objectid="99909" data-objecttype="102" href="https://community.nxp.com/docs/DOC-99909">Where to post a Discussion?</A> </P><P></P><P>Thank you for using Freescale Community.</P></BODY></HTML> Tue, 29 Apr 2014 08:46:13 GMT https://community.nxp.com/t5/i-MX-Processors/PF0100-SW1A-B-output-voltage/m-p/300782#M37792 Wlodek_D_ 2014-04-29T08:46:13Z Re: PF0100 SW1A/B output voltage https://community.nxp.com/t5/i-MX-Processors/PF0100-SW1A-B-output-voltage/m-p/300783#M37793 <HTML><HEAD></HEAD><BODY><P>Hi Muthu Nagarajan,</P><P></P><P><SPAN style="background: white;">Yes, by default, the 1.375V from SW1AB_VOLT</SPAN><SPAN style="background: white;"> for the F3 version</SPAN> <SPAN style="background: white;">is in the sequence of</SPAN><SPAN style="background: white;"> SW1AB_SEQ</SPAN><SPAN style="background: white;"> =</SPAN><SPAN style="background: white;"> 2.</SPAN><SPAN style="background: white;"> This means that the </SPAN><SPAN style="background: white;">PF0100 SW1A/B output voltage of 1.375V will be enabled about 0.5 to 4.0 ms </SPAN>(depending on the tD4 configuration (Table 11 of the datasheet)) after the SW2 Turn-on, even if the internal LDO_ARM in the iMX6SL is enabled.</P><P></P><P>About bypassing the internal LDO_ ARM in the i.MX6SL, yes, it is possible to bypass it for normal operation and about the <SPAN style="background: white;">SW1A/B and SW1C output voltages, these are programmable from 0.300 to 1.875 V in steps of 25 mV.
