i.MX RT internal LDO and DC/DC converter's specification

[masahirokiniwa]

I checked the data sheet and reference manual for i.MX RT 1050, but I couldn't find some specifications.

Could you tell me below specifications?

<DC/DC converter>

 - Switching frequency

 - Radiation noise on the reference circuit (i.MX RT1050 EVK)

<LDO>

 - PSRR : Power Supply Rejection Ratio

If I can find them by other documents, could you tell me them?

Best regards,
