MP7752GF-Z 概述
A Class-D audio amplifier converts a comparatively low-power analog input into a high-efficiency PWM power stage that delivers energy directly to the speaker load. The MP7752 integrates 240 mOhm power MOSFETs, eliminating the need for external output inductors and reducing board area. Its fixed-frequency architecture supports filterless operation when the system does not require a reconstructed low-pass signal at the speaker output.
Verified features include a 2 x 15 W BTL output configuration, two pairs of differential inputs, short-circuit protection, startup and shutdown pop suppression, automatic mute or no-noise switching, automatic power saving, and 90% efficiency. The listed THD is 0.5%, with a -60 dB figure and 100 dB also appearing in the verified distributor listing, although the exact test conditions for those entries require confirmation in the manufacturer datasheet.
The MP7752GF-Z is suitable for compact stereo audio products, multimedia speakers, USB or Bluetooth audio accessories, soundbars, and powered speaker systems. Its differential input architecture helps reject common-mode noise when the source is balanced or when a suitably designed input network is used. The exposed-pad package supports thermal performance, but actual output power and distortion depend strongly on supply voltage, speaker impedance, PCB copper, thermal design, and load tolerance.
The key design consideration is the exposed thermal pad. Place the pad over a continuous ground or thermal-copper area with multiple short vias and follow the manufacturer land pattern. Decouple the supply locally, keep speaker outputs away from sensitive input routing, and validate EMI performance because Class-D PWM outputs contain high-frequency energy. Confirm all absolute maximum ratings, pin functions, thermal resistance values, and application limits against the official datasheet before release.

典型应用
MP7752GF-Z 适用于 6 应用s: Compact Stereo Speaker, Bluetooth Speaker, USB Audio Speaker, Multimedia Speaker System, Powered Bookshelf Speaker, Soundbar Speaker Module.
Compact Stereo Speaker
The MP7752GF-Z fits a compact stereo speaker because it delivers the verified 2 x 15 W into 8-ohm BTL output from a 5 V to 18 V supply while integrating the power MOSFETs. Placing the two channels close to the speaker connectors reduces output-loop area and helps control EMI. The 28-pin TSSOP-EP still requires a carefully designed exposed-pad land pattern, local supply decoupling, and speaker-current copper sized for the load.
推荐
Bluetooth Speaker
The MP7752GF-Z is suitable for the power stage of a Bluetooth speaker because its analog differential inputs can receive audio from a codec while its integrated 240 mOhm MOSFETs reduce external output hardware. The verified 2 x 15 W capability is useful for portable or compact stereo enclosures, but the power budget must include codec efficiency, battery regulation, speaker sensitivity, thermal rise, and peak music demand rather than only nominal amplifier rating.
推荐
USB Audio Speaker
A USB audio speaker can use the MP7752GF-Z after a USB audio interface or codec converts digital audio to analog differential signals. The 5 V to 18 V supply range accommodates common low-voltage systems, while the 90% listed efficiency helps reduce amplifier-stage power loss. A practical design must keep USB clock and data routing away from speaker outputs, provide adequate bulk and ceramic decoupling, and verify EMI compliance with the enclosure and cable configuration.
推荐
Multimedia Speaker System
The MP7752GF-Z is well matched to multimedia and desktop speaker systems that need stereo output without a large discrete power stage. Its BTL topology avoids a direct speaker connection to ground, while the integrated MOSFETs simplify the output path. The design should still include input filtering, DC-blocking or biasing strategy appropriate to the source, output EMI testing, and thermal validation because Class-D edge energy can couple into sensitive analog sections.
推荐
Powered Bookshelf Speaker
The MP7752GF-Z can serve as the power amplifier in a compact powered bookshelf speaker when the design targets 8-ohm loads and the verified 15 W-per-channel class is adequate. Its exposed thermal pad provides a path for heat dissipation, but sustained high-level playback requires a PCB copper area and enclosure airflow or heat spreading matched to ambient temperature. Use the official datasheet for maximum output conditions and do not infer thermal margin from the 90% efficiency figure alone.
推荐
Soundbar Speaker Module
The MP7752GF-Z is applicable to a compact soundbar or audio-module design needing two amplified channels in one package. The verified 2 x 15 W rating provides a useful starting point for 8-ohm stereo loads, while differential inputs can help reject shared-ground noise. Soundbar placement also makes EMI and thermal design important: route BTL speaker outputs with short, matched paths, isolate PWM-current returns from microphone or control circuitry, and test radiated emissions at the finished-enclosure level.

设计说明
The exposed pad is the primary thermal path for the MP7752GF-Z. Follow the MPS land pattern and connect the pad to the recommended thermal copper and via arrangement. Estimated: using the listed 90% efficiency, the amplifier-stage loss at 30 W total output is approximately 3.33 W before considering input-stage and board losses; actual dissipation depends on test conditions. Verify junction temperature and thermal resistance against the manufacturer data.
Place local supply decoupling immediately across the amplifier supply pins and use short, wide traces for Class-D output-current paths. Keep the exposed-pad vias close to the thermal pad and provide a continuous copper region beneath the package. Avoid placing sensitive analog or microphone traces beneath speaker-output routing. The verified data does not provide exact capacitor values or via counts, so use the official reference layout and impedance/ripple requirements.
Class-D outputs carry high-frequency switching energy even when the speaker hears only the intended audio band. Route each BTL output as a short pair with minimal loop area, maintain symmetric speaker connections, and test radiated emissions with the final speaker cable and enclosure. The manufacturer describes advanced EMI performance, but layout, cable length, power-supply impedance, and board grounding determine the finished product’s result.
Do not treat the 2 x 15 W rating as a guarantee for every speaker impedance, supply voltage, or thermal environment. The verified data specifically identifies 8-ohm, 5 V to 18 V operation. Confirm minimum load impedance, absolute maximum supply, speaker wiring protection, startup behavior, and exposed-pad requirements in the manufacturer datasheet before connecting a different load or changing the supply rail.
