TOP261 switch mode power supply smps circuit previous post TDA8920 Class-D Amplifier Circuit power supply
The smps power supply of the amplifier, as is indicated must have a few output voltages. This source must be powerful enough to be able to cover the power demands of the terminal degree. The source can be realized as linear, or as a source of power. Each of these types of sources has its advantages and disadvantages.
Among the positive characteristics of switching power supply belongs to high the efficiency, small dimensions and low weight. The disadvantage is the complicated construction due to the source of the linear. Linear sources have a lower efficiency and at high power they have the large dimensions and high weight . To implement the source for the switching power output stage was selected the source of the switching concept. The advantage of this resources will also be relatively simple realization of the multiple output branches with different voltages.
Smps Circuit
Proposal for engagement with the TOP261 smps Proposal for the involvement of auxiliary components for proper operation of the smps circuit was used the program PIExpert smps desing. Input data for this software are the type of smps circuit, the output voltage and the desired performance. The output is the overview diagram with the recommended values of the components.

TDA8920 Class-D Amplifier Circuit
TDA8920 Class-D circuit is to use two circuits TDA8920 in bridge mode connection (BTL). Circuit TDA8920 works with the internal oscillator, whose frequency can be set using the the external elements. The manufacturer recommends that, in the application of multiple circuits in a single device to use for synchronization of circuits external oscillator.

Smps Netzteil des Verstärkers, wie Sie angegeben ist, muss ein paar Ausgangsspannungen. Diese Quelle muss stark genug sein, um in der Lage sein, zur Deckung des Energiebedarfs der terminal Grad. Die Quelle kann realisiert werden als linear, oder als eine Quelle der Kraft. Jede dieser Arten von Quellen hat vor-und Nachteile.
