Description Supply decoupling for the power supply pins. For optimum performance, these components should be located close to the TC2000/TP2050 and returned to their respective ground as shown in the Application/Test Circuit. Zobel capacitor, which in conjunction with RZ, terminates the output filter at high frequencies. Use a high quality film capacitor capable of sustaining the ripple current caused by the switching outputs. Zobel resistor, which in conjunction with CZ, terminates the output filter at high frequencies. The combination of RZ and CZ minimizes peaking of the output filter under both no load conditions or with real world loads, including loudspeakers which usually exhibit a rising impedance with increasing frequency. The recommended power rating is 1 Watt. Output inductor, which in conjunction with CO, demodulates (filters) the switching waveform into an audio signal. Forms a second order filter with a cutoff frequency of f C = 1 ( 2 L O C O ) and a quality factor of Q = R L C O L O C O . Output capacitor, which in conjunction with LO, demodulates (filters) the switching waveform into an audio signal. Forms a second order low-pass filter with a cutoff frequency of f C = 1 ( 2 L O C O ) and a quality factor of Q = R L C O L O C O . Use a high quality film capacitor capable of sustaining the ripple current caused by the switching outputs. Electrolytic capacitors should not be used. High-frequency bypass capacitor for VCC - GND on each supply pin. A 50V rating is required for this component. Optional snubber capacitor, which in conjunction with RSN, reduces overshoot on non-optimal layouts. Only required if switching output overshoot is above rated voltage of TP2500. Use low-dissipation type (NPO). Optional snubber resistor, which in conjunction with CSN, reduces overshoot on nonoptimal layouts. Only required if switching output overshoot is above rated voltage of TP2500. Required 1/4 Watt rating. Differential mode capacitor.

Tri path Technol og y, I nc. - Techni cal I nformation
APPLICATION INFORMATION Basic Operation
The TP2050 is a MOSFET output stage that level-shifts the signal processor's 5V switching patterns to the power supply voltages and drives the power MOSFETs. The power MOSFETs are complementary N-channel/P-channel devices configured in full-bridges and are used to supply power to the output load. The outputs of the power MOSFETs must be low pass filtered to remove the high frequency switching pattern. A residual voltage from the switching pattern will remain on the speaker outputs when the recommended output LC filter is used, but this signal is outside of the audio band and will not affect audio performance.
Circuit Board Layout
The TP2050 is a power (high current) power stage that operates at relatively high switching frequencies. The output of the amplifier switches between VCC and GND at high speeds while driving large currents. This high-frequency digital signal is passed through an LC low-pass filter to recover the amplified audio signal. Since the amplifier must drive the inductive LC output filter and speaker loads, the amplifier outputs can be pulled above the supply voltage and below ground by the energy in the output inductance. To avoid subjecting the TP2050 to potentially damaging voltage stress, it is critical to have a good printed circuit board layout. It is recommended that Tripath's layout and application circuit be used for all applications and only be deviated from after careful analysis of the effects of any changes. The following components are important to place near their associated TP2050 pins and are ranked in order of layout importance, either for proper device operation or performance considerations. The capacitors CHBR provide high frequency bypassing of the amplifier power supplies and will serve to reduce spikes across the supply rails. CHBR should be kept within 1/8" (3mm) of the VCC pins. Please note that the four VCC pins must be decoupled separately. In addition, the voltage rating for CHBR should be 50V as this capacitor is exposed to the full supply range. Similarly, capacitors CS should be located as close as possible to their respective pins on the TP2050.
In general, to enable placement as close to the TP2050, and minimize PCB parasitics, the capacitors listed above should be surface mount types (with the exception of the bulk CHBR capacitor).
TP2050 Output Capability
The TP2050 can drive two 8 Ohm loads with 40 Watts each at less than 0.05% THD+N. The maximum sustained amplifier output power will be determined by a number of factors including the TP2050 junction temperatures, the load impedance and the power supply voltage. Tripath does not recommend driving loads below 6 Ohms single ended as the amplifier efficiency will be reduced and the amplifier will reach it's current limit at relatively low power output levels. With the outputs connected in parallel, however, the TP2050 is capable of driving single channel loads down to 4 Ohms with very high power capability.
Paralleled Outputs
For stereo mode operation, the TP2050 is a dual full bridge. For parallel mode operation, the TP2050 can be configured as a single full bridge with double current capability by connecting the CONFIG pin to the VDD pin of the TP2050. Please refer to the Application/Test Diagram for parallel operation.

Output Filter Design
Tripath amplifiers generally have a higher switching frequency than PWM implementations, allowing the use of higher cutoff frequency filters and reducing the load dependent peaking/drooping in the 20kHz audio band. This is especially important for applications where the end customer may attach any speaker to the amplifier (as opposed to a system where speakers are shipped with the amplifier), since speakers are not purely resistive loads and the impedance they present changes over frequency and from speaker model to speaker model. An RC network, or "Zobel" (RZ, CZ) should be placed at the filter output to control the impedance "seen" by the TP2050 when not attached to a speaker load. The TP2050 works well with a 2nd order, 80kHz LC filter with LO = 10uH and CO = 0.47uF and RZ = 10 Ohm/1W and CZ = 0.47uF. NOTE: Output inductor selection is a critical design step. The core material and geometry of the output filter inductor affects the TP2050 distortion levels, efficiency, power dissipation and EMI output. Please contact Tripath Applications for additional information about recommended inductor sources.
Protection Circuits
The TP2050 is protected against over-current, over / under-voltage and over-temperature conditions.
Over-temperature Protection
An over-temperature fault occurs if the junction temperature of the part exceeds approximately 150C. The thermal hysteresis of the part is approximately 25C, therefore the fault will automatically clear when the junction temperature drops below 125C.
Performance Measurements of the TK2050
The TP2050 operates by generating a high frequency switching signal based on the audio input. This signal is sent through a low-pass filter (external to the Tripath amplifier) that recovers an amplified version of the audio input. The frequency of the switching pattern is spread spectrum in nature and typically varies between 100kHz and 1MHz, which is well above the 20Hz - 20kHz audio band. The pattern itself does not alter or distort the audio input signal, but it does introduce some inaudible components. The measurements of certain performance parameters, particularly noise related specifications such as THD+N, are significantly affected by the design of the low-pass filter used on the output as well as the bandwidth setting of the measurement instrument used. Unless the filter has a very sharp roll-off just beyond the audio band or the bandwidth of the measurement instrument is limited, some of the inaudible noise components introduced by the TP2050 amplifier switching pattern will degrade the measurement. One feature of the TP2050 is that it does not require large multi-pole filters to achieve excellent performance in listening tests, usually a more critical factor than performance measurements. Though using a multi-pole filter may remove high-frequency noise and improve THD+N type measurements (when they are made with wide-bandwidth measuring equipment), these same filters degrade frequency response. The TP2050 Evaluation Board uses the Application/Test Circuit of this data sheet, which has a simple two-pole output filter and excellent performance in listening tests. Measurements in this data sheet were taken using this same circuit with a limited bandwidth setting in the measurement instrument.
