UM-WI-006 NDA Confidential DA16200 H/W Design Guide Introduction This document provides a set of guidelines that help users prepare schematics and PCB layouts for products with the DA16200. Recommended schematic, chip interfaces, and surrounding components as well as PCB layout guidelines of both devices are provided.
UM-WI-006 NDA Confidential DA16200 H/W Design Guide Power Supply 2.2.1 Power Management The DA16200 has one internal DC-DC converter and multiple LDOs to supply power to all internal sub-blocks. Power management performs the on-off control of these regulators and is implemented through the register setting inside the RTC block.
