Bits

Bit Name

R/W

Description

Channel selection for

volt-second balance

control

R/W

Setting this bit selects Channel A or Channel C for volt-second balance control.

0 = use Channel C for volt-second balance control.

1 = use Channel A for volt-second balance control.

Volt-second balance

control limit

R/W

This bit sets the modulation limit on the duty cycles from the volt-second control circuit.

0 = maximum volt-second control modulation is ±160 ns.

1 = maximum volt-second control modulation is ±80 ns.

These bits set the volt-second balance control loop gain.

loop gain

R/W

Sensing selection for

current balance

R/W

Setting this bit selects CS1_A/CS1_B or CS2_A/CS2_B for current balance control.

0 = use CS2_A/CS2_B for current balance control.

1 = use CS1_A/CS1_B for current balance control.

Current balance

control limit

R/W

This bit sets the modulation limit on the duty cycles from the current control circuit.

0 = maximum current control modulation is ±160 ns.

1 = maximum current control modulation is ±80 ns.

These bits set the current balance control loop gain.
