APPLICATION NOTE:
(ref. fig. 7)
Modular Application (more Devicesin Parallel)
The use of the modular application lets very high
power be delivered to very low impedance loads.
The modular application implies one device to act
as a masterand the others as slaves.
The slave power stages are driven by the master
device and work in parallel all together, while the
input and the gain stages of the slave device are
disabled, the figure below shows the connections
required to configure two devices to work to-
gether.
The master chip connections are the same as
the normal single ones.
The outputs can be connected together
with-
out the need of any ballast resistance.
The slave SGND pin must be tied to the nega-
tivesupply.
The slave ST-BY pin must be connected to
ST-BY pin.
The bootstrap lines must be connected to-
gether and the bootstrap capacitor must be in-
creased: for N devices the boostrap capacitor
mustbe 22
μ
F timesN.
The slave Mute and IN-pins must be grounded.
THE BOOTSTRAP CAPACITOR
For compatibility purpose with the previous de-
vices of the family, the boostrap capacitor can be
connectedboth between the bootstrappin (6) and
the output pin (14) or between the boostrap pin
(6) and the bootstraploader pin (12).
