Description
Reserved.
If voltage line feedforward is enabled, this bit disables it during the reference ramp-up (soft
start). This operation is gated by the filter GO bit (Register 0x7F[3]).
0 = feedforward enabled during soft start (recommended setting).
1 = feedforward disabled during soft start.
This bit enables the voltage line feedforward loop. This operation is gated by the filter GO bit
(Register 0x7F[3]).
0 = feedforward disabled.
1 = feedforward enabled.
These bits set the gain for the voltage feedforward function.

Description
Setting this bit enables modulation from balance control on the OUTA rising edge, t
recommended to allow volt-second balance on edges that are between 0 ns to 640 ns of the
switching period.
0 = positive sign. Increase of balance control modulation moves t
1 = negative sign. Increase of balance control modulation moves t
Setting this bit enables modulation from balance control on the OUTA falling edge, t
recommended to allow volt-second balance on edges that are between 0 ns to 640 ns of the
switching period.
0 = positive sign. Increase of balance control modulation moves t
1 = negative sign. Increase of balance control modulation moves t
Setting this bit enables modulation from balance control on the OUTB rising edge, t
recommended to allow volt-second balance on edges that are between 0 ns to 640 ns of the
switching period.
0 = positive sign. Increase of balance control modulation moves t
1 = negative sign. Increase of balance control modulation moves t
Setting this bit enables modulation from balance control on the OUTB falling edge, t
recommended to allow volt-second balance on edges that are between 0 ns to 640 ns of the
switching period.
0 = positive sign. Increase of balance control modulation moves t
