Power supply

TDA2030A

18/23

Doc ID 1459 Rev 2

Even if, with a regulated supply, higher output power can be obtained (VS is constant in all

operating conditions), the additional cost and power dissipation do not usually justify its use.

Using non-regulated supplies, there are fewer design restrictions. In fact, when signal peaks

are present, the capacitor filter acts as a flywheel, supplying the required energy. In average

conditions, the continuous power supplied is lower. The music power/continuous power ratio

is greater in this case than for the case of regulated supply, with space saving and cost

reduction.
