Startup
SLEEP Mode
Pull PWREN high to operate in ACTIVE mode. Pull PWREN low to operate in SLEEP mode. Buck1/4 turn off in SLEEP
mode. Buck2/3 regulate to VSET1 in SLEEP mode.
DVS Mode
This CMI does not have true DVS functionality. See the different GPIO functions to see which ones control a buck
converter’s output voltage.
POK Thresholds
POK_UV = 2.77V
POK_OV = 3.76V
PG
The PG pin is not used and can be left open or pulled to GND.
POK
POK is configured as an input to select the Buck4 output voltage. When POK is L, VSET1 sets Buck4 to 1.2V. When
POK is H, VSET0 sets Buck1 to 1.8V.
EXT_EN
The EXT_EN pin is not used and should be left open.
nRESET
The nRESET pin is configured as the Buck2 POK open drain output with 0ms delay.
nRESET_AUX1
The nRESET_AUX1 pin is programmed as an open drain output. It goes high 1989us after Buck4 goes into regulation.
