11 Power Supply Recommendations

The TPA6204A1 is designed to operate from an input voltage supply range between 2.5 V and 5.5 V. Therefore, the output voltage range of power supply must be within this range and well regulated. The current capability of upper power must not exceed the maximum current limit of the power switch. TI recommends placing decoupling capacitors in every voltage source pin. Place these decoupling capacitors as close as possible to the TPA6204A1.

11.1 Power Supply Decoupling Capacitor

The TPA6204A1 device requires adequate power supply decoupling to ensure a high efficiency operation with low total harmonic distortion (THD). Place a low equivalent series resistance (ESR) ceramic capacitor, typically 0.1 µF, as close as possible of the VDD pin. This choice of capacitor and placement helps with higher frequency transients, spikes, or digital hash on the line. Also is recommended to place a 2.2-µF to 10-µF capacitor on the VDD supply trace. This larger capacitor acts as a charge reservoir, providing energy faster than the board supply, thus helping to prevent any droop in the supply voltage.
