... STA530 DESCRIPTION (continued) In fact it's permits to build a BASH® architecture amplifier adding only few external components and a variable Buck regulator tracking the audio signal. Notice that normally only one Buck regulator is used to supply a mul- tichannel amplifiers system , therefore most of the functions implemented in the circuit have a summing output pin ...

... STA530 OUTPUT BRIDGE The Output bridge amplifier makes the single-ended to Differential conversion of the Audio signal using two power amplifiers, one in non-inverting configuration with gain equal to 10 and the other in inverting configuration with unity gain. To guarantee the high input impedance at the input pins, PWR_Inp1....4, the second amplifier stages are driven by the output of the first stages respectively. In 60W x2 channel configuration the " ...

... This means that the highest of any given output is the output that determines the tracking signal. The absolute value circuit inside the STA530 has gain. This makes it possible to use an RC network and a re- sistor divider to create a phase shift in the tracking signal at higher frequencies. This is also useful in optimizing the alignment of the buck regulator's output with the output signal of the bridge amplifier at high frequency This circuit first converts the buck switch current to a peak voltage ...

... R For example in the STA530 the Rth jc is 1°C/W. R case-to-heatsink with grease is about 0.5 °C/W. The maxi- mum operating junction temperature is 130 °C, which for margin should be derated to 120 °C. Buck Regulator Heatsink The Buck regulator heatsink can be designed in a similar manner and does not change by varying power supply. ...
