Power Supply Design for NXP i.MX 7 Using the TPS65023

 284 次查看

This document details the design considerations of a power management unit solution for the NXP i.MX 7 processor using the TPS65023 power management IC (PMIC).

The TPS65023 has an input range from 2.5 to 6 V. The device has three low-dropout (LDO) regulators and three step-down converters that provide the 1-, 1.35-,1.8-, 3-, and 3.3-V rail signals in the appropriate power-on and power-off sequence that is required by the i.MX 7. For an i.MX 6 power solution please refer to the VVDN design on RadiumBoards website.
