Hello
The PWM frequency set internally in TPS92520 is abnormal. We use the combination of TPS92682 + TPS92520, with 2-phase boost and 6-phase buck. There is no problem using the default PWM frequency. When using 215Hz and the duty cycle is 20%, the actual test frequency is 113Hz and the duty cycle is 8%. could you give me an explation for this ?
The parameter settings are as follows:
TPS92682 boost 50.8v
switching frequency: 178kHz
TPS92520 switching frequency: 437kHz
thank you
best regards
