2.4 Powering i.MX 8M Plus and LDDR4

This section shows an example of how the TPS6521905 PMIC and 0.85 V discrete power switch can power the i.MX 8M Plus, DDR4 and peripherals. TPS6521905 is a user-programmable PMIC that comes with all the rails disabled by default and can be customized to meet the requirements of different use cases.

Note: Refer to Section 3 to learn more about how this PDN can be modified to support SNVS low power mode.
