Dear team,
For each SWx output of PF1510, each has SWx_TMODE_SEL bit.
I think this bit depicts the controlling method of MOSFET’s turn-on/off time controlling methods. (default setting is; controlling T-ON)
By changing the SWx_TMODE_SEL into 1 from 0, the MOSFET is controlled based on turn off time.
Am I correct?
Best Regards,

You can simply understand either TON or TOFF control in PWM waveforms generated from comparator (VOUT compares with VREF).
TON control provides better transient response and low duty cycle stability. TOFF mode control is used for high duty cycles.
