The aim of the Tracking Power Supply (TPS) Audio Object is to provide PWM duty cycle values to boosted power supply controller ICs, as well as providing a reference to adjust TPS output on extension amplifiers or micro-controllers managing discrete amplifiers. This results in changing the power amplifier supply voltage in accordance to the levels of the audio output signals. Adaptive supply voltage allows to increase the efficiency and decrease electromagnetic noise generated by the amplifiers.<\/p>\n
The TPS Audio Object has the following additional parameters:<\/p>\n
AMPFACTOR<\/span> – Amplification factor. Describes mapping of float numbers into output voltage The tuning parameters of the TPS Audio Object are listed below<\/p>\n AUDIODELAY<\/span> – Delay Buffer length The parameters must match the hardware specification and the integration will be different among platforms. Please refer to the appropriate platform integration guide and specifications.<\/p>\n","protected":false},"excerpt":{"rendered":" The aim of the Tracking Power Supply (TPS) Audio Object is to provide PWM duty cycle values to boosted power supply controller ICs, as well as providing a reference to adjust TPS output on extension amplifiers or micro-controllers managing discrete amplifiers.
