Analog Power Supplies and Load Switching
Seven different analog supply voltages are generated from the Unreg DC. All of
these are used on the A4 RF board and some are used on the A5 system board.
Some sections of the circuitry on the A4 RF board may be switched to low
power modes to conserve power and minimize heat. This is accomplished
through load switching. See
“Power Management Circuitry” on page 5-8
for
more information.
