Integrated Power Supply Reference Design for
NXP i.MX 6ULL
Description
This reference design is a fully functional development
board powering an NXP™ i.MX 6ULL application
processor from a TPS6521815 PMIC. The hardware
design consists of DDR3L SDRAM (512 MB), 32-MB
Serial NOR Flash, 8-GB eMMC 5.0 iNAND, SD Card
interface v3.0, dual-channel 100Base-T Ethernet, 5-
channel USB hub with Type-A ports, micro-AB USB
OTG, mountable LCD screen, and expansion
connector for additional inputs and outputs. This
design is intended to be used as a reference for data
concentrator projects in grid communications or for
any project using the i.MX 6ULL, i.MX 6ULZ, or i.MX
6UltraLite processor that requires evaluation of
alternative power solutions.
