Other Parts Discussed in Thread: TPS63020
Hello team,
My customer is verifying the behavior when R1 removing or R2 shorting between GND and FB. In these case, Vout is calculated as max value from equation 1 in datasheet. This should make maximum duty cycle, right?
The customer got scope short of Vout on their target board. This waveform is repeatedly output.
Is this expected behavior?
After this experiment, Vout got normal operation with correct R1 and R2 resister. This means the circuit works well.
Could you please give your comment.
Best regards,
Katsu
