SLAS558 – OCTOBER 2007
FR-4 Glass Epoxy material with 2 oz. (70
μm) is recommended for use with the TAS5342L. The use of this
material can provide for higher power output, improved thermal performance, and better EMI margin (due to
lower PCB trace inductance.
The large capacitors used in conjunction with each full-birdge, are referred to as the PVDD Capacitors. These
capacitors should be selected for proper voltage margin and adequate capacitance to support the power
requirements. In practice, with a well designed system power supply, 1000
μF, 50-V will support more
applications. The PVDD capacitors should be low ESR type because they are used in a circuit associtated with
high-speed switching.
In order to design an amplifier that has robust performance, passes regulatory requirements, and exhibits good
audio performance, good quality decoupling capacitors should be used. In practice, X7R should be used in this
application.
The voltage of the decoupling capactors should be selected in accordance with good design practices.
Temperature, ripple current, and voltage overshoot must be considered. This fact is particularly true in the
selection of the 0.1
μF that is placed on the power supply to each half-bridge. It must withstand the voltage
overshoot of the PWM switching, the heat generated by the amplifier during high power output, and the ripple
current created by high power power output. A minimum voltage rating of 50-V is required for use with a 32.0 V
power supply.
The following schematics and PCB layouts illustrate "best practices" in the use of the TAS5342L.
