9 Power Supply Recommendations

Absolute Maximum Ratings discusses most of the requirements on TAS5630B power supply. There are a few more important guidelines that should be considered. The most important parameters are the absolute maximum rating on PVDD pins, bootstrap pins and output pins. Over stress the device with higher that maximum voltage rating may shorten device lifetime operation and even cause device damage. Be sure that the specifications in section 6 are observed. For best audio performance, low ESR bulk capacitors are recommended. Depending on the application 470-µF capacitor or higher should be used. As always, decoupling capacitors must be placed no more than 1 mm from the power supply pins. If PCB space is not allowed for close decoupling capacitor placement, the decoupling capacitors can be placed on the back side of the device with vias. However, it still needs to be right below the pins.
