We find TPS92690PWPR/NOPB PIN has Ringingeffect, want to reduce it.
And want to know what cause it?
Design feature:
Vin 16.8v
Vout 40v
F=402Khz
Rt=105k
PWM=3Khz
Part Number: TPS92690 Hello Sir,
if apply PWM 200Hz 0.5% duty to PIN1 nDIM, the backlight turns on after 22seconds,
if apply PWM 200Hz grater than 10% to PIN1 nDIM, the backlight turns on in 3 seconds,
is any suggestion of it.
the attached picture shows…
