VDD1 dc-dc Regulator
4.1.1.1
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 in
power-down mode when it is not in use. Table 4-3 describes the regulator characteristics.

(3)
Output voltage must discharge the load current completely and settle to its final value within 100
μs.
(4)
Load current varies proportionally with the output voltage. The slew rate is for increasing and decreasing voltages, and the maximum
load current is 1.1 A.
