Figure 29. Type 2 buck regulator block diagram
Buck regulator SW5 uses 5 bits to set the output voltage. The VSW5[4:0] sets the output
voltage during the run and the standby mode.
The SW5 is designed to have a fixed voltage thought all the system operation. In the
event a system requires this regulator to change its output voltage during the system-
on states, when the SW5 is commanded to change its voltage via the I2C command, the
output is discharged first and then enabled back to the new voltage level as stated in the
VSW5[4:0] bits.
The default output voltage configuration for the run and the standby modes is loaded
from the OTP_VSW5[4:0] registers upon power up.
