Note:
1. Due to internal dropout, the DC-DC output will never be able to reach its input voltage, VVREGVDD
.
2. LP mode controller is a hysteretic controller that maintains the output voltage within the specified limits.
3. LPCMPBIASEMxx refers to either LPCMPBIASEM234H in the EMU_DCDCMISCCTRL register or LPCMPBIASEM01 in the
EMU_DCDCLOEM01CFG register, depending on the energy mode.
4. Drive levels are defined by configuration of the PFETCNT and NFETCNT registers. Light Drive: PFETCNT=NFETCNT=3; Medi-
um Drive: PFETCNT=NFETCNT=7; Heavy Drive: PFETCNT=NFETCNT=15.
5. Output voltage under/over-shoot and regulation are specified with CDCDC 4.7 µF. Different settings for DCDCLNCOMPCTRL
must be used if CDCDC is lower than 4.7 µF. See Application Note AN0948 for details.
