BoostVSet[4:0]
BoostVSet[4:0]
Boost Output Voltage Setting. This setting is internally latched and can change only when boost is disabled.
2.5V to 5.0V, linear scale, 100mV increments
000000 = 2.5V
000001 = 2.6V
…
011001 = 5.0V
> 011001 = 5.0V

BoostEMI
BoostSeq[2:0]
Boost Enable Configuration (Read-Only)
000 = Disabled
001 = Reserved
010 = Enabled at 0% of Boot/POR Process Delay Control
011 = Enabled at 25% of Boot/POR Process Delay Control
100 = Enabled at 50% of Boot/POR Process Delay Control
101 = Reserved
110 = Controlled by HVEN (MAX14750)
111 = Controlled by BoostEn [1:0] after 100% of Boot/POR Process Delay Control (MAX14720)
BoostEn[1:0]
Boost Enable Configuration (effective only when BoostSeq[2:0] == 111)
00 = Disabled. Active discharge behavior depends on BoostActDsc.
01 = Enabled
10 = Enabled when MPC is high
11 = Reserved
BoostEMI
BoostInd
Boost EMI reduction. Dampens ringing of the inductor when in discontinuous mode
0 = EMI damping active (improve EMI)
1 = EMI damping disabled (improve Efficiency)
Boost Inductance Select
1 = Inductance is 3.3µH
0 = Inductance is 4.7µH
0
