stereo efficient,digital amplifier power stage for driving speakers up to100 W/2Ωin mono.The high efficiency of the TPA3130D2allows it to do2×15W without external heat sink on a single layer PCB.The TPA3118D2can even run2×30W/8Ωwithout heat sink on a dual layer PCB.If even higher power is needed the TPA3116D2does2×50W/4Ωwith a small heat-sink attached to its top side PowerPAD.All three devices share the same footprint enabling a single PCB to be used across different power levels.The TPA31xxD2advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interferences;this is achieved together with an option of either master or slave option,making it possible to synchronize multiple devices.The TPA31xxD2devices are fully protected against faultswith short-circuit protection and thermal protection as well as overvoltage,undervoltage,and DC protection.Faults are reported back to the processor to prevent devices from being damaged during overload conditions.Device Information(1)PART NUMBER PACKAGE BODY SIZE(NOM) TPA3116D2DAD(32)11.00mm×6.20mm TPA3118D2TPA3130D2DAP(32)11.00mm×6.20mm(1)For all available packages,see the orderable addendum atthe end of the datasheet.Simplified Application CircuitCopyright © 2016,Texas Instruments IncorporatedTPA3116D2,TPA3118D2,TPA3130D2SLOS708G–APRIL2012–REVISED DECEMBER2017 7.3.13Efficiency:LC Filter Required with the Traditional Class-D Modulation SchemeThe main reason that the traditional class-D amplifier-based on AD modulation needs an output filter is that the switching waveform results in maximum current flow.This causes more loss in the load,which causes lower efficiency.The ripple current is large for the traditional modulation scheme,because the ripple current is proportional to voltage multiplied by the time at that voltage.The differential voltage swing is2×VCC,and the time at each voltage is half the period for the traditional modulation scheme.An ideal LC filter is needed to store the ripple current from each half cycle for the next half cycle,while any resistance causes power dissipation.The speaker is both resistive and reactive,whereas an LC filter is almost purely reactive.The TPA3116D2modulation scheme has little loss in the load without a filter because the pulses are short and the change in voltage is VCC instead of2×VCC.As the output power increases,the pulses widen,making the ripple current larger.Ripple current could be filtered with an LC filter for increased efficiency,but for most applications the filter is not needed.An LC filter with a cutoff frequency less than the class-D switching frequency allows the switching current to flow through the filter instead of the load.The filter has less resistance but higher impedance at the switching frequency than the speaker,which results in less power dissipation,therefore increasing efficiency.7.3.14Ferrite Bead Filter ConsiderationsUsing the Advanced Emissions Suppression Technology in the TPA3116D2amplifier it is possible to design a high efficiency class-D audio amplifier while minimizing interference to surrounding circuits.It is also possible to accomplish this with only a low-cost ferrite bead filter.In this case it is necessary to carefully select the ferrite bead used in the filter.One important aspect of the ferrite bead selection is the type of material used in the ferrite bead.Not all ferrite material is alike,so it is important to select a material that is effective in the10to100MHz range which is key to the operation of the class-D amplifier.Many of the specifications regulating consumer electronics have emissions limits as low as30MHz.It is important to use the ferrite bead filter to block radiation in the30MHz and above range from appearing on the speaker wires and the power supply lines which are good antennas for these signals.The impedance of the ferrite bead can be used along with a small capacitor with a value in the range of1000pF to reduce the frequency spectrum of the signal to an acceptable level.For best performance,the resonant frequency of the ferrite bead/capacitor filter should be less than10MHz.Also,it is important that the ferrite bead is large enough to maintain its impedance at the peak currents expected for the amplifier.Some ferrite bead manufacturers specify the bead impedance at a variety of current levels.In this case it is possible to make sure the ferrite bead maintains an adequate amount of impedance at the peak current the amplifier will see.If these specifications are not available,it is also possible to estimate the bead current handling capability by measuring the resonant frequency of the filter output at low power and at maximum power.A change of resonant frequency of less than fifty percent under this condition is desirable.Examples of ferrite beads which have been tested and work well with the TPA3130D2can be seen in the TPA3130D2EVM user guide SLOU341.A high quality ceramic capacitor is also needed for the ferrite bead filter.A low ESR capacitor with good temperature and voltage characteristics will work best.Additional EMC improvements may be obtained by adding snubber networks from each of the class-D outputs to ground.Suggested values for a simple RC series snubber network would be18Ωin series with a330pF capacitor although design of the snubber network is specific to every application and must be designed taking into account the parasitic reactance of the printed circuit board as well as the audio amp.Take care to evaluate the stress on the component in the snubber network especially if the amp is running at high PVCC.Also,make sure the layout of the snubber network is tight and returns directly to the GND pins on the IC.Submit Documentation

TPA3116D2has been tested with a simple ferrite bead filter for a variety of applications including long speaker wires up to125cm and high power.The TPA3116D2EVM passes FCC class-B specifications under these conditions using twisted speaker wires.The size and type of ferrite bead can be selected to meet application requirements.Also,the filter capacitor can be increased if necessary with some impact on efficiency. There may be a few circuit instances where it is necessary to add a complete LC reconstruction filter.These circumstances might occur if there are nearby circuits which are sensitive to noise.In these cases a classic second order Butterworth filter similar to those shown in the figures below can be used.Some systems have little power supply decoupling from the AC line but are also subject to line conducted interference(LCI)regulations.These include systems powered by"wall warts"and"power bricks."In these cases,LC reconstruction filters can be the lowest cost means to pass LCI mon mode chokes using low frequency ferrite material can also be effective at preventing line conducted interference.4- 8W W4- 8W WTPA3116D2,TPA3118D2,TPA3130D2SLOS708G–APRIL2012–REVISED DECEMBER2017Submit Documentation FeedbackFigure35.TPA31xxD2Output Filters7.3.16AM Avoidance EMI ReductionTo reduce interference in the AM radio band,the TPA3116D2has the ability to change the switching frequency via AM<2:0>pins.The recommended frequencies are listed in Table6.The fundamental frequency and its second harmonic straddle the AM radio band listed.This eliminates the tones that can be present due to the switching frequency being demodulated by the AM radio.Table6.AM FrequenciesUS EUROPEANSWITCHING FREQUENCY(kHz)AM2AM1AM0 AM FREQUENCY(kHz)AM FREQUENCY(kHz)522-540540-917540-914500001917-1125914-1122600(or400)0100001125-13751122-13735000011375-15471373-1548600(or400)010000 1547-17001548-1701600(or500)010001TPA3116D2,TPA3118D2,TPA3130D2 SLOS708G–APRIL2012–REVISED DECEMBER2017Submit Documentation Feedback。
