TAS5630DKD - 300W Stereo Class-D Amplifier | Texas Instruments
Référence : TAS5630DKD ✓ ActifTAS5630DKD Présentation
A Class-D amplifier is a switching audio power stage in which the output transistors operate at high frequency and deliver speaker current with high efficiency. In the amplifier hierarchy, the TAS5630 belongs to the audio amplifier IC category, then to the Class-D amplifier group and finally to the power-amplifier IC class. Its integrated closed-loop feedback is intended to reduce distortion associated with conventional open-loop Class-D output stages, while retaining the efficiency benefits of switching conversion.
The main performance attributes are up to 300 W stereo output, up to 600 W mono operation, 4 Ω to 8 Ω speaker compatibility, and a 50 V power-stage supply assumption. The manufacturer documentation also shows a 10.8 V to 13.2 V signal-supply range in its application description. The 44-HSSOP package provides a large thermal connection area, but power capability depends on the heat sink, thermal interface material, copper area, board construction, and ambient conditions rather than package marking alone.
PurePath HD technology is the defining architectural feature. The TI product page identifies the TAS5630 as a high-performance analog-input Class-D amplifier with integrated closed-loop feedback. Analog input allows compatibility with conventional line-level audio signals, while the integrated feedback arrangement supports a power-stage design intended for high-output applications. The manufacturer specifically recommends a low-noise, low-output-impedance 12 V regulator for the signal supply and a low-impedance, low-noise 50 V power-stage supply.
Typical uses include professional power amplifiers, high-power stereo audio systems, cinema and home-theater speaker amplification, and bridged mono installations for subwoofers or full-range speakers. The device is particularly relevant where a single power amplifier must support both stereo and bridged-mono configurations, although the external supply, output-filter, speaker, and thermal designs remain application-specific.
Thermal design is the principal implementation constraint. The exposed package heat slug must be coupled to a suitable heat sink through a high-performance thermal interface material, and the power stage requires stable, low-impedance supplies. Use the application diagrams in the manufacturer datasheet to select inductors, capacitors, power-supply components, and the PCB thermal interface for the intended output impedance and power level.
This page organizes the manufacturer specifications, verified source links, application guidance, and replacement considerations into an engineering-focused reference. It also distinguishes confirmed package and output capabilities from parameters that require direct checking in the TI datasheet before schematic release, PCB construction, or production procurement.

Applications typiques
TAS5630DKD convient pour 6 applications: Professional Stereo Power Amplifier, Bridged Mono Subwoofer Amplifier, Home Theater Multi-Channel Amplifier, Stage and Performance Audio System, High-Power Audio Speaker System, Automotive or Industrial Audio Module.
Professional Stereo Power Amplifier
The TAS5630DKD fits a high-power professional stereo amplifier because it can deliver up to 300 W per channel into 4 Ω to 8 Ω speakers while accepting an analog audio input. Place the device at the output stage of a preamplifier or mixer, then follow the manufacturer application diagrams for output filtering and feedback connections. Its 44-HSSOP package requires a properly sized heat sink and thermal interface material. The key engineering tradeoff is heat: the documented power capability depends on the thermal configuration, so continuous full-power operation requires careful validation of the power-stage supply, board copper, and heat-sink temperature rise.
Recommandé
Bridged Mono Subwoofer Amplifier
The TAS5630DKD can be configured for bridged mono operation with up to 600 W output into the documented 4 Ω to 8 Ω load range. This topology is useful for a powered subwoofer or high-output monitor when one bridged power stage is preferred to two independent channels. Because the Class-D output is switching, the PCB must include the required output-filter network and keep the power loop compact. Do not treat the 600 W figure as an unconditional speaker rating; verify continuous output, thermal behavior, protection circuitry, and load tolerance under the final enclosure conditions.
Recommandé
Home Theater Multi-Channel Amplifier
The TAS5630DKD is suitable for a compact multi-channel home-theater power stage when each channel must drive a 4 Ω to 8 Ω loudspeaker at substantial output power. Its analog-input architecture accepts conventional line-level audio, while PurePath HD integrated closed-loop feedback identifies it as a high-performance Class-D implementation. A practical design should allocate heat-sinking area around each exposed slug, maintain a low-impedance 50 V power-stage rail, and use the TI application circuit as the basis for filtering and layout. Validate several amplifier modules together because concentrated channel loading can raise enclosure temperatures and stress every power supply.
Recommandé
Stage and Performance Audio System
The TAS5630DKD can serve as the main power amplifier in a stage, club, or live-performance system requiring high output into conventional 4 Ω to 8 Ω speakers. Its documented capability of up to 300 W stereo supports high-volume playback, while the analog input allows connection to a mixer or DSP output. The exposed heat slug makes thermal coupling a central part of the mechanical design rather than an afterthought. Use a substantial heat sink, high-performance thermal interface, and low-impedance power supply, and perform thermal testing at realistic ambient temperature before deployment.
Recommandé
High-Power Audio Speaker System
The TAS5630DKD is appropriate for a high-power passive speaker system where the objective is to drive 4 Ω to 8 Ω loads with substantial analog audio power. Its Class-D architecture provides an efficient path from the preamplifier output to the speaker terminals, while integrated closed-loop feedback is the defining PurePath HD feature. The system design must include the prescribed output filters, robust speaker protection, controlled startup, and a low-noise power-stage supply. The maximum stereo rating of 300 W should be treated as a configuration-dependent capability because heat-sink performance and PCB thermal construction determine the sustainable operating level.
Recommandé
Automotive or Industrial Audio Module
The TAS5630DKD can be evaluated for industrial or mobile audio modules that need high analog-input output power from a dedicated Class-D stage. Its 10.8 V to 13.2 V signal-supply range and 50 V power-stage arrangement fit systems where a clean amplifier rail is available, but the module must provide substantial heat dissipation and robust transient control. Before automotive deployment, confirm qualification, vibration, temperature, protection, and electromagnetic-compatibility requirements directly with the manufacturer. For industrial equipment, provide enclosure ventilation or a conduction path to the exposed heat slug and include speaker disconnection protection in the final design.

Notes de conception
Couple the exposed heat slug to a properly sized heat sink using high-performance thermal interface material, as directed by the TI application information. The 300 W stereo and 600 W mono ratings are configuration-dependent, so validate the final assembly at the target ambient temperature and speaker load. Monitor heat-sink temperature, provide copper area beneath and around the HSSOP, and avoid enclosing the amplifier without a deliberate conduction or airflow path.
Use the manufacturer-recommended low-noise, low-output-impedance 12 V signal supply and low-impedance 50 V power-stage supply. The TI datasheet specifically identifies the 12 V rail as a regulator output and requires the power-stage rail to have low noise and low impedance. Place high-frequency bypass and power-loop components close to the device, and validate the supply under simultaneous full-power channel loading.
Base the PCB on the TI application diagrams and preserve the recommended output-filter and feedback layout. Keep the Class-D switching loop compact, route the exposed heat slug to the heat-sink interface without restrictive necking, and maintain low-impedance power and ground returns. Component placement, trace width, copper layers, and via arrays should be scaled from the manufacturer's guidance for the intended output power and thermal construction.
Do not treat the 300 W or 600 W headline values as guaranteed continuous ratings without validating the heat sink, thermal interface, PCB, supply, and enclosure. Also avoid using TAS5616DKD or TAS5630B variants as automatic substitutions: verify the complete pinout, supply limits, output-current capability, and thermal requirements first. The available family comparison establishes similarity, but not universal drop-in equivalence.
