hello i have one quesion about the TPS92692
information: buck-boost circuit input voltage 9-16V, LED current: 0.34A*duty（0.4）=0.136A
when the input votage reach 12v， The waveform of GATE pin is shown in the following figure：
When I cancel PWM dimming, it's still like this
please help Analyze the reason ,the ywllow is the SW voltage ,and the bule is the GATE vlotage.
thank you
bset regards
