Tool/software:
Hello,team
I set TPS92682 in single channel about constant current mode,use Sepic toplogy,when I use the internal PWM dimming ,it is current is abnormally as we want(detail see the waveform),
as I know, the IC already solve the current overshoot issue use by the internal circuit,I don't know why I still occur a high current overshoot in internal PWM dimming.
could you teach me how to solve it?made the PWM dimming waveform like the Design Guide: TIDA-050029.
my circuit simiar with the demo,only some value change.
bule is MOS VDS,yellow is LED current,this waveform is base on 500mA with 10% duty.
when I check the Design Guide: TIDA-050029,it is waveform is not a overshoot current, so this waveform is I want,if the issue is cause by software,could you share the TIDA-050029 demo code to me
