MP7770GF-Z 概要
What is a Class-D audio amplifier? A Class-D amplifier is an audio power amplifier whose switching output stage delivers energy to a speaker more efficiently than a traditional linear Class-A/B design. The MP7770 uses MPS proprietary variable-frequency topology to combine high output power with compact integration. It supports either two single-ended speaker channels or one bridge-tied-load speaker, making it adaptable to stereo and compact high-power audio systems.
The MP7770 integrates 100 mOhm power MOSFETs, startup and shutdown pop-elimination circuitry, and short-circuit protection. According to the manufacturer product page, its fully integrated amplifier architecture reduces solution size. The MP7770GF is also available on the EV7770-F-00A evaluation board for single-ended configurations, providing a practical platform for evaluating 45 W per channel into 4 Ohm speakers at up to 36 V VDD.
The manufacturer datasheet identifies the MP7770GF family as an analog Class-D audio amplifier with variable-frequency operation. The output topology determines the power configuration: two channels can each deliver 45 W into 4 Ohm speakers in single-ended mode, while a bridged configuration can deliver 90 W into 8 Ohm. The bridge-tied-load topology is useful when the system requires one higher-power speaker output rather than two independent channels.
Typical applications include compact stereo audio systems, multimedia speakers, powered subwoofers, consumer audio equipment, and industrial or communications speaker systems. When designing the board, provide a clean supply path, adequate thermal copper around the exposed pad, and speaker protection appropriate to the selected output topology.
The most important design tradeoff is power delivery versus thermal and supply capability. At 36 V VDD, the stated output ratings are 45 W per channel or 90 W in bridged mode, but actual continuous output depends on speaker impedance, supply voltage, thermal conditions, and the amplifier's operating limits. This page consolidates the verified product data, comparison fields, alternatives, and design guidance relevant to MP7770GF-Z.
According to the verified data, MP7770GF-Z is offered as a 28-TSSOP-EP Class-D audio amplifier by Monolithic Power Systems and is associated with the MP7770GF family.

主な用途
MP7770GF-Z の用途: 6 件s: Compact Stereo Speaker, High-Power Mono Subwoofer, Powered Multimedia Speaker, Consumer Audio Hub, Industrial Speaker Driver, Portable Audio Product.
Compact Stereo Speaker
The MP7770GF-Z is suitable for compact stereo speakers because it provides 45 W per channel into 4 Ohm speakers in single-ended mode under a 36 V VDD supply. Place the amplifier near the speaker connector and power input to minimize board-current loops, while using the integrated 100 mOhm power MOSFETs and short-circuit protection to reduce external circuitry. The 28-TSSOP-EP package requires careful exposed-pad thermal design. In a real enclosure, continuous output depends on supply capability, speaker sensitivity, airflow, and the PCB copper area, so prototype thermal testing is essential.
おすすめ
High-Power Mono Subwoofer
For a mono subwoofer, the MP7770GF-Z can be configured in bridge-tied-load operation to deliver 90 W into an 8 Ohm speaker at 36 V VDD. This configuration removes the need for two external speaker outputs but requires correct BTL wiring and careful common-mode and layout review. The amplifier should be supplied from a power rail capable of handling the audio output current, and the speaker should have suitable transient protection. Because the verified data does not provide thermal resistance or frequency-response limits, those values must be confirmed in the manufacturer datasheet before production release.
おすすめ
Powered Multimedia Speaker
The MP7770GF-Z fits powered multimedia speakers that need analog Class-D amplification from a compact board. Its selectable 2 x 45 W stereo or 90 W BTL architecture lets one amplifier family support both conventional stereo enclosures and higher-power single-speaker designs. The integrated startup and shutdown pop-elimination feature helps control audible transitions during power cycling, while short-circuit protection adds system-level robustness. Designers should still validate EMI, speaker-wire length, grounding, and thermal performance in the final mechanical enclosure.
おすすめ
Consumer Audio Hub
MP7770GF-Z can provide the speaker-drive stage in a consumer audio hub or compact amplified speaker platform. The verified manufacturer page emphasizes solution-size reduction through integrated power MOSFETs and protection circuitry, allowing more PCB area for signal processing and connectivity. Use a clean, decoupled supply path and route the high-current output returns carefully to minimize switching-related disturbance in nearby analog sections. The device supports both single-ended stereo and bridged mono operation, enabling one platform family to address different enclosure and speaker configurations.
おすすめ
Industrial Speaker Driver
The MP7770GF-Z can be considered for powered industrial speaker systems operating from a suitably designed low-voltage bus. Its 36 V VDD capability and dual operating modes provide flexibility for distributed audio products, while variable-frequency Class-D operation can improve efficiency compared with a discrete linear output stage. The integrated short-circuit protection is valuable when speakers use long cables or removable connectors. Final qualification should include transient immunity, ground-fault behavior, thermal cycling, and acoustic testing because the verified snippets do not provide those system-level specifications.
おすすめ
Portable Audio Product
For portable or compact audio products, the MP7770GF-Z offers a high-power Class-D output stage in a surface-mount 28-TSSOP-EP package. The choice between stereo single-ended and mono BTL operation lets a designer match the amplifier topology to battery, adapter, or automotive-style supply requirements. A portable design must account for supply transients, heat dissipation, speaker impedance, and audible startup behavior. The verified data confirms pop-elimination circuitry and short-circuit protection, but battery-current limits and thermal-rise calculations require application-specific measurements.

設計ノート
The MP7770GF-Z is a surface-mount audio power amplifier with a thermally exposed package. Estimated: the verified 90 W bridged output is a stated datasheet configuration at 36 V VDD, not a guaranteed dissipation value. Actual device loss depends on output waveform, supply voltage, modulation method, speaker impedance, and efficiency. Use the exposed pad as a thermal path, distribute copper where permitted, and verify junction temperature in the assembled enclosure rather than relying only on the package rating.
Keep the high-current VDD and speaker-output paths short and wide, and place input, supply, and output decoupling according to the manufacturer reference layout. Bridge-tied-load wiring must not connect either output to ground or chassis unintentionally. Route analog input traces away from switching output nodes, use a compact return path, and check that the exposed-pad solder and thermal interface meet assembly requirements.
Size the supply rail for the selected configuration rather than only the nominal output wattage. The verified ratings are 45 W per channel into 4 Ohm at 36 V VDD in single-ended mode and 90 W into 8 Ohm in BTL mode. Speaker sensitivity, peak program material, cable resistance, and audio headroom can increase supply demand. Add appropriate bulk and local decoupling and validate transient response with an oscilloscope.
Do not treat a functionally similar Class-D amplifier as a drop-in replacement without verifying every pin, exposed-pad connection, supply limit, speaker configuration, and thermal condition. In particular, TPA3255DDVR, MAX98090AEWJ+T, and TAS5711PHPR use different packages in the verified data. The available cross-reference results do not establish pin compatibility, so a redesign or board-level qualification is required.
コンプライアンス情報
The verified data identifies a lead-free packaging attribute in a distributor listing but does not explicitly provide current RoHS, REACH, halogen-free, or conflict-minerals declarations.
