1. The switching frequency is 2.4 MHz±10%
2. Including line transient and load transient.
3. These characteristics are given for SMPSEXTHP bit is set in the PWR_CR3 register.
The SMPS current consumption can be determined using the following formula based on the maximum LDO
current consumption provided in Section 6.3.7 Supply current characteristics:
IDDSMPS=IDDLDO× VCORE÷ VDD×efficency
where
IDDLDO is the current in LDO configuration given in the following tables
VCORE is the digital core supply (VCAP)
Efficiency is defined in the following curves.
