楼上指DC-DC还是LDO?
整颗IC最低能通过I2C调到0.8V(DC-DC2)
Step-down PFM/PWM DC-DC converters
o DC-DC1: normal 3.3V, range is 2.8V-3.5V,
IMAX=1100mA, support inductance-less
mode (IMAX=600mA)
o DC-DC2: normal 1.2V or 1.8V (Pin-option),
range is 0.8V-1.4V, or 1.4V-2.0V, 950mA
o DC-DC3: normal 2.5V or 1.8V (Pin-option),
range is 2.0V-2.7V or 1.3V-2.0V, 900mA
Low dropout (LDO) regulators
o LDO1: Fixed 1.25V, or 3.3V (Pin-option),
20mA, always enable
o LDO2: 3.0V, range is 2.8V-3.1V, 150mA
o LDO3: 1.8V or 2.5V (Pin-option), range is
1.6V-1.9V or 2.3V-2.6V, 400mA
o LDO4: 3.3V, range is 2.7V-3.3V, 200mA
o LDO5: 3.3V, range is 2.5V-3.3V, 200mA |
