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

masahirokiniwa — Wed, 30 Jan 2019 05:27:16 GMT

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?

- 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,

M.Kiniwa
