DC-DC5 Converter Mode
0 = Boost mode
1 = Switch mode
Reset by state machine.
DC-DC5 Hibernate behaviour:
0 = Continue as in Active state
1 = Disable converter output
Reset by state machine.
DC-DC5 Hibernate signal select
00 = HIBERNATE register bit
01 = L_PWR1
10 = L_PWR2
11 = L_PWR3
Note that Hibernate is also selected when a GPIO
Hibernate input is asserted.
Reset by state machine.
DC-DC5 peak current limit select
0 = Higher peak current
1 = Lower peak current
Reset by state machine. Default held in metal
mask.
DC-DC5 compensation ramp
{DC5_RMPH, DC5_RMPL}
00 = 20V < VOUT ≤ 30V
01 = 10V < VOUT ≤ 20V
10 = 5V < VOUT ≤ 10V
11 = VOUT ≤ 5V (will be chosen automatically if
DC5_FBSRC=11)
Reset by state machine. Default held in metal
mask.

Reset by state machine. Default held in metal
mask.
DC-DC5 voltage feedback selection
00 = voltage feedback (using external resistor
divider on pin FB5)
01 = current sink ISINKA used as feedback
101 0110 = 3.0V
100 1110 = 2.8V
……
