Hi Non-Isoloage DC/DC team
We tested SW output and LDO output for really load test on TPS54122-EVM as a chart below
I searhed LDO Dropout Voltage on datasheet, However I can't search SW Output Dropout Voltage on datasheet
SW Output [1.2V] |
LDO Output [3.3V] |

Can I get Product test value? And, Are you okay our result test Value?
We think that Droput voltage so big on SW output drop voltage.
