Part Number:TPS54335A

Dear support member,

My customer used TPS54335A.
I have a question about UVLO.

(Situation)
R1(VIN - ENpin):430kΩ
R2(EN pin -GND):33kΩ

Calculated of Datasheet
Vsart:17.3V
Vstop:13.5V

Measurement result
Vsart:17.3V
Vstop:12.5V


(Question)
When the input voltage is 12.5 V, the output voltage is turned off.
It is different from the calculation result. (Vstop: 13.5 V)
What is the cause?


Best regard.
Bob Lee.
