Hello,

I am going to use MKW36A512VFT4 in my Automotive upcoming Project.

I have read the datasheet and found that there are options in Power configuration, By pass mode and Buck mode.

Buck Mode :- As per Datasheet," In Buck mode, DC-DC converter will generate 1.8V at VDD_1P8OUT and 1.5V at VDD_1P5OUT_PMCIN pins. VDD_1P8OUT should supply to VDD1, VDD2 and VDDA. VDD_1P5OUT_PMCIN should supply to VDD_RF1 and VDD_RF2. VDDXTAL can be either supplied by 1.5V or 1.8V. "

My Thought :- For that need to Supply 3.3V at Pins - DCDC_CFG, PSWITCH and VDCDC_IN.

If I want to use Bypass, So I will connect Pins as mentioned below,

1) PSWITCH to GND

2) DCDC_CFG to 3.3V,

3) VDCDC_IN to 3.3V,

4) VDD_0 & VDD_1 to 3.3V,

5) VDD_RF1, RF2, RF3 to 3.3V.

But what should I do with Pins - VDD_1P8OUT & VDD_1P5OUT_PMCIN. Should I leave them floating?

Please suggest me to use MKW36A512VFT4 in Bypass mode and suggest correct connections if It have made wrong in my details.

Regards,

Alpesh
