TS4956
Application information
42/55
The efficiency is the ratio between the output power and the power supply.
The maximum theoretical value is reached when VPEAK = VCC/2, so
In modes 3 and 4, the TS4956 has two active output power amplifiers. Each amplifier
produces heat due to its power dissipation. Therefore the maximum die temperature is the
sum of each amplifier’s maximum power dissipation. It is calculated as follows.
Pdiss 1 = power dissipation due to the first power amplifier.
Pdiss 2 = power dissipation due to the second power amplifier.
Total Pdiss =Pdiss 1 +Pdiss 2 (W)
In most cases, Pdiss 1 =Pdiss 2, giving:
4.3.3
BTL output configuration (modes 1, 2, 7)
The average current delivered by the supply voltage is:

The power delivered by the supply voltage is:
Then, the power dissipation by each amplifier is:
