Product data sheet
14.6 Device synchronization
14.7 Thermal behavior (printed-circuit board considerations)
Where:
Example:
Substituting R1 = R2 = 4.7 k , Z
results in a gain of G
If two or more TDA8932B devices are used in one application it is recommended that all
devices are synchronized running at the same switching frequency to avoid beat tones.
Synchronization can be realized by connecting all OSCIO pins together and configuring
one of the TDA8932B devices as master, while the other TDA8932B devices are
configured as slaves (see
A device is configured as master when connecting a resistor between pins OSCREF and
V
oscillator output for synchronization. The OSCREF pins of the slave devices should be
shorted to V
The TDA8932B is available in two different thermally enhanced packages:
The SO32 package has special thermal corner-leads, increasing the power capability
(reducing the overall R
and 32) should be attached to a copper plane. The SO32 package is very suitable for
applications with limited space for a thermal plane (in a single layer PCB design).
