DESCRIPTION
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.
DC-DC5 voltage feedback selection
00 = voltage feedback (using external resistor
divider on pin FB5)
01 = current sink ISINKA used as feedback
10 = current sink ISINKB used as feedback
11 = voltage feedback (using internal resistor
divider on pin USB)
Reset by state machine. Default held in metal
mask.
