Notes
23. Throughout this document, there are references to non-Freescale components. Freescale does not assume liability, endorse, or warrant
components from external manufacturers that are referenced in circuit drawings or tables. While Freescale offers component
recommendations in this configuration, it is the customer’s responsibility to validate their application.
24. To operate the VDDQ as a 1.5 V buck regulator, the recommended resistors, RFBDDQ15_1 and RFBDDQ15_2 are needed in the
feedback path, as shown in Figure 28.
