Texas Instruments TIDA-050038 Design Manual

Design Guide: TIDA-050038
Integrated Power Supply Reference Design for NXP i.MX
8M Mini Processor
Description
TIDA-050038 is a system-on-module (SoM)
development board integrating two TI PMICs,
TPS6521825 and LP873347, with the NXP™ i.MX 8M
Mini Application Processor. The hardware design also
includes LPDDR4 SDRAM (2GB, x32-bit), QSPI NOR-
Flash (32MB), 16GB eMMC 5.1, 32-kHz RTC
oscillator, WiFi + Bluetooth module, and 9-channel
current monitoring. The SoM board is compatible with
the 8MMiniLPD4-EVK base board for full system
evaluation. This design is intended for any project that
is using the i.MX 8M Mini or i.MX 8M Nano processor
and requires evaluation of alternate power solutions.
