Hello,
My customer is testing the performance of LTM4677 thru DC2481B-A (ADI EVM).
Their test condition is like below and they added R7 (0ohm) between Vin and Inrvcc as the guide in schematic because of applying 5V at Vin .
Test Condition : Vin 5V / Vout 1V
The guide in schematic: WHEN VIN < 5.75V, SHORT INTVCC TO VIN WITH R7=0 0hm
But they can't get any output voltage at Vout when they applied 5V at Vin.
And then after removing R7 and changing Vin to 5.6V, they can get normal output voltage (1V).
Is there any fault to use DC2481B-A EVM?
How to get 1V at Vout when they applied 5V at Vin?
Regards,
Se-woong
