Hello,
In your EVM - ADC12JQ1600 EVM you are using for the DC-DC conversion - from 5V to 2.2V, 1.4V, and 1.1V the TPS2652268 device.
Can we use X3 TPSM82864A instead - noise wise.
Regards,
Giora
Hello Giora,
The reason this is done is to use buck converters to switch down from a common 12V input to appropriate levels to ensure the correct voltage drop occurs over the LDOs to maximize the PSRR of the LDOs.
You do not have to follow this, we do this to simplify our EVMs power tree.
Best,
Eric
