TAS5630BPHD

Overview

The TAS5630BPHD is a high-performance analog input Class-D audio amplifier from Texas Instruments, utilizing PurePath HD integrated feedback technology. It delivers up to 300 W of stereo output power or 400 W in mono configuration when driving 4-ohm loads with a single 50 V supply. Key electrical parameters include a THD+N of 0.03%, an 80 kHz signal bandwidth, and greater than 88% efficiency. The device operates within a supply voltage range of 25 V to 52.5 V and features a 64-pin HTQFP package designed for thermal enhancement.

Feature Summary

• Integrates PurePath HD closed-loop feedback architecture to achieve ultra-low distortion comparable to traditional Class-AB amplifiers while maintaining high Class-D efficiency.
• Supports multiple output configurations including stereo BTL, mono PBTL, and 2.1 channel setups on a single PCB using fill options.
• Features advanced self-protection mechanisms including under-voltage lockout, over-temperature shutdown, clipping detection, and short-circuit protection with error reporting.

Applications

• Mini component systems
• AV receivers
• DVD receivers
• Active speakers

Procurement Notes

Verify the specific suffix 'PHD' against the official datasheet to confirm the 64-pin HTQFP package variant. Confirm current lifecycle status as components may be subject to obsolescence notices. Ensure thermal interface material specifications are compatible with the exposed pad design for optimal heat dissipation during high-power operation.

Selection Notes

Select this model for applications requiring high-fidelity audio reproduction with minimal distortion at high power levels. The integrated feedback loop simplifies design by reducing the need for external compensation networks. Consider the 64-pin package size and thermal requirements when designing the PCB layout to ensure adequate heat sinking for sustained 300 W stereo performance.

Part Context

This component belongs to the TAS5630 family of high-power audio amplifiers. It shares core PurePath HD technology with variants like the TAS5630BDKD but differs in packaging and pin count. The PHD variant specifically offers a QFP footprint suitable for different board space constraints compared to the PSOP packages used in other family members.

Replacement Considerations

The TAS5630BDKD is a related variant within the same family offering similar performance characteristics but utilizes a 44-pin HSSOP package instead of the 64-pin HTQFP. Verify pin-to-pin compatibility and thermal management requirements before substituting, as the package differences impact mounting and heat dissipation strategies.
