INCREASING AVAILABLE POWER
The ADuM6000 device is designed to work in combination
with other compatible isoPower devices. The RC
RC
another device through its RC
also receive a PWM signal from another device through its RC
pin and act as a slave to that control signal. The RC
whether the part acts as a master or slave device.
When the ADuM6000 acts as a slave, its power is regulated
by the master device, allowing multiple isoPower parts to be
combined in parallel while sharing the load equally. When the
ADuM6000 is configured as a master or standalone device, it
generates its own PWM feedback signal to regulate itself and
any slave devices.
The ADuM6000 can function as a master, slave, or standalone
device. All devices in the ADuM5xxx and ADuM6xxx family
can function as standalone devices. Some of these devices also
function as master devices or slave devices, but not both (see
Table 14).
Table 15 illustrates how isoPower devices can provide many
combinations of data channel count and multiples of the single-
unit power.

Another feature that is allowed by the RC
architecture is the ability to completely shut down the oscillator
in the dc-to-dc converter. This places the part in a low power
standby mode and reduces the current draw to a fraction of a
milliamp.
When the ADuM6000 is placed in slave mode by driving RC
low, the oscillator is controlled by RC

mode. With no oscillator driving power to the secondary side,
