DC-DC3 Soft-Start Control
(Current limiting is stepped through 4
intermediate steps.)
00 = Immediate start-up
01 = 4 x 400us (1600us total)
10 = 4 x 4ms (16ms total)
11 = 4 x 40ms (160ms total)
DC-DC3 Current Limit
Sets the maximum DC output current in
Hysteretic Mode
00 = 100mA
01 = 200mA
10 = 400mA
11 = 800mA
Protected by user key.
DC-DC3 Output Capacitor
00 = 10uF to 20uF
01 = 10uF to 20uF
10 = 22uF to 45uF

DC-DC3 ON Voltage select
DC3_ON_VSEL[6:0] selects the DC-
DC3 output voltage from 0.85V to 3.4V
in 25mV steps.
DC3_ON_VSEL[6:2] also exist in
DBE/OTP memory, controlling the
voltage in 100mV steps.
DC3_ON_VSEL[6:0] is coded as
follows:
00h = 0.85V
01h = 0.875V
…
65h = 3.375V
66h to 7Fh = 3.4V
