6.1.1 VDD1 DC-DC Regulator
6.1.1.1 VDD1 DC-DC Regulator Characteristics
The VDD1 DC-DC regulator is a stepdown DC-DC converter with a configurable output voltage. The
programming of the output voltage and the characteristics of the DC-DC converter are SmartReflex
compatible. The regulator can be put in sleep mode to reduce its leakage (PFM) or power-down mode
when it is not being used. Table 6-2 describes the regulator characteristics.
