Power Management Unit

DA16200 has one internal DC-DC converter and several LDOs to supply power to all internal sub-

blocks. Power management does the on-off control of these regulators and is implemented through

the register setting inside the RTC block.

Details of the internal DC-DC converters and LDOs are explained below:

● DC-DC converter: from the power supply of external VBAT input, it generates 1.4 V power for the

digital LDO and RF block

● LDO for digital Blocks: from the DC-DC output, it generates 1.1 V power which is used for digital

blocks

● LDO for I/O and external flash memory:

○ This LDO output is used only for 1.8 V digital I/O applications

○ From external VBAT power input, it generates 1.8 V output voltage which is used for digital

I/O power domain in 1.8 V digital I/O applications

○ It is also used for external flash memory

○ For 3.3 V digital I/O applications, external power (3.3 V) is directly supplied for digital I/O

power

● FDIO_LDO_OUT supports only 1.8 V

With the internal DC-

DC converters and LDOs, all the power necessary for DA16200’s internal sub-

blocks are sufficiently generated.
