How do you set the slope of the slope compensation circuit in the ISL81601?
Hi,
I will be back with an update.
Thanks, and regards

Thanks. I am waiting for a response to this question.
If possible, I would appreciate it if you could respond by December 16th.
Best regards.
ISL81601 doesn't have adjustable slope compensation. It's fixed inside the IC. ISL78227 has adjustable slope compensation. But it's a Boost controller. Kindly tell me you application.

I am using ISL81601 in reverse mode with Vin_min＝2.2V and Vout=12V, i.e. boost mode. The maximum load current is 4.5A. Under these conditions, the switching waveform becomes unstable when the load is 900mA or more. I thought that the slope compensation was not working properly.
You can simulate the IC using this software: ISL81601 - 60V Bidirectional 4-Switch Synchronous Buck-Boost Controller | Renesas. You might have to tune COMP pin.
How do I simulate in reverse mode? All the simulation models on HP seem to be in forward mode.
Thanks.
Based on your requirements you can modify the simulation to achieve reverse mode operation.
Thanks, and regards,
