Tool/software:
I am using the TPS92692 in buck-boost mode with an analog signal to set Iadj and PWM. When I start the circuit, it consistently goes into fault mode and the fault pin is periodically set low. However, after about 5 seconds, everything works fine and the fault pin is no longer set low but after some time, the current also gradually decreases.
The input voltage is 24V and the circuit powers 7 LEDs (with a forward voltage ranging from 2.8V to 3.4V for each LED). In this case, Iadj is set to 1.46V and the PWM is 2.44V
Here is the circuit :
Current start-up signal :
Fault pin start-up signal :
Current after about 5s :
