Dear Support member,
My customer made TPS40170 board.
My customer evalued to down the input power supply.
When UVLO voltage lower than Input voltage, Vout, SW, SS voltage starts to drop.
But a phenomenon occured in which the SS voltage falls to 0 V and rises up to 1.4 V again.
Is this phenomenon as expected and behavior of the device?
When UVLO voltage lower than Input voltage,
Although the output voltage and SW voltage are falling,
As the SS voltage rises, the SW voltage rises and the output voltage also rises.
Specification condition.
Vin：48V
Vout：24V
Iout：5A
fsw：300kHz
UVLO on：30.9V
UVLO off：28.9V
Best regard.
Bob Lee.
