BuckCfg
Buck Configuration
0 = set to 0 for burst mode
1 = set to 1 for FPWM mode
BuckInd
Buck Inductance Select
0 = Inductance is 2.2µH
1 = Inductance is 4.7µH
BuckHysOff
Buck Hysteresis Off
0 = Enable comparator hysteresis
1 = Disable comparator hysteresis (recommended to reduce voltage ripple)
BuckMinOT
Buck Minimum On-Time
0 = Enable deglitch delay on comparator for better efficiency
1 = Disable deglitch delay on comparator to minimize voltage ripple
BuckInteg
Buck Integrate
0 = Helps stabilize the buck regulator for high currents with small output capacitor
1 = Better load regulation at high current (recommended for output capacitance > 6µF)
0
