µs

Time from EM2 to EM0

TEM2_EM0

Time from EM2 exit until DCDC

enters EM0 mode (i.e, EM0 BIAS,

IPK, and voltage target settings

are applied, but the output voltage

target may still be transitioning if

there was a voltage target change

from EM2 to EM0).

Time from EM2 exit until DCDC

enters EM0 mode and EM0 output

target voltage is reached. Buck

= 1.0 V, VOB_EM0 =1 .2 V,

BK_IPK = 16, VDDB = 3.0 V

Time from EM4 to EM2

TEM4_EM2

Time from EM4 exit until until

DCDC begins switching in EM2

mode. During this period, no addi-

tional load should be applied to

the DCDC output

Time from EM4 exit until DCDC

begins switching in EM2 mode
