MP7752GF 概要
An inductorless Class D amplifier is a switching audio amplifier that uses integrated power MOSFETs to deliver high output power efficiently while driving speakers directly in a bridge-tied-load arrangement. The MP7752GF belongs to the amplifier-IC, audio-amplifier, Class D, and power-management semiconductor hierarchy. Its integrated power stage, short-circuit protection, start-up/shutdown pop elimination, and advanced EMI performance support compact consumer audio products.
The verified source data identifies the MP7752GF as a 2-channel stereo Class D amplifier rated at 18 V and 2 x 15 W. It integrates 240 milliohm power MOSFETs and uses bridge-tied-load output topology. The fixed-frequency switching architecture removes the need for an external output inductor, reducing board area compared with conventional filter-based Class D solutions. The exposed-pad package also provides a thermal connection from the power stage to the PCB.
Typical applications include compact stereo speakers, portable consumer audio products, multimedia systems, USB or docking audio products, and other low-voltage audio equipment requiring efficient amplification. In a typical bridge-tied-load implementation, the two amplifier outputs drive the two speaker terminals, so the speaker load sees differential voltage rather than being connected to ground.
The principal design consideration is thermal management. Although the integrated MOSFETs eliminate external output inductors, Class D switching and bridge-tied-load operation still generate heat that must leave through the exposed pad and surrounding copper. PCB thermal vias, adequate copper area, and careful placement of input, power, and output connections are important for reliable operation.
This product page combines the verified distributor description, manufacturer datasheet identification, package information, and cross-reference results. Pricing, exact operating conditions, protection thresholds, efficiency curves, and complete pin-level electrical characteristics must be confirmed against the manufacturer datasheet before design release.

主な用途
MP7752GF の用途: 6 件s: Compact Stereo Speaker, Portable Audio Product, Docking Speaker, Multimedia Speaker, USB Audio Accessory, Consumer Audio Amplifier Board.
Compact Stereo Speaker
The MP7752GF fits compact stereo-speaker products because it provides 2 x 15 W Class D output in a 28-pin TSSOP exposed-pad package. Its analog input and bridge-tied-load arrangement allow the two channels to drive left and right speakers without conventional output inductors, helping reduce board area. The integrated 240 milliohm power MOSFETs, short-circuit protection, and start-up/shutdown pop elimination support a compact power stage. Designers must still provide the manufacturer-recommended input network, supply decoupling, thermal-pad copper, and output routing, and should verify the speaker impedance against the tested datasheet conditions.
おすすめ
Portable Audio Product
The MP7752GF is suitable for portable and compact audio systems requiring efficient stereo amplification from an 18 V-class supply. Its inductorless Class D architecture reduces external magnetics, while the integrated power stage supports a compact PCB implementation. The verified 2 x 15 W rating makes the device relevant for small speakers, docks, and multimedia products. Because the data does not provide battery-current, efficiency, thermal, or shutdown specifications, battery-life and enclosure calculations must use the manufacturer datasheet. Protection, input coupling, speaker wiring, and start-up behavior should be validated in the final product.
おすすめ
Docking Speaker
A docking speaker can use the MP7752GF as a two-channel, bridge-tied-load audio power stage with 2 x 15 W output capability. The exposed-pad package and integrated MOSFETs support a compact assembly, while the inductorless architecture can simplify board planning compared with designs requiring external Class D output inductors. The fixed-frequency Class D topology should be evaluated for EMI in the complete dock, especially around the speaker leads, power supply, and enclosure openings. Use the manufacturer’s recommended PCB layout and verify thermal performance with the actual speaker load, ambient temperature, and enclosure.
おすすめ
Multimedia Speaker
The MP7752GF is applicable to multimedia speakers requiring integrated stereo amplification and fixed-frequency Class D operation. The 2 x 15 W rating and two-channel BTL architecture suit conventional left/right speaker layouts, while the 28-pin TSSOP-EP package allows a compact surface-mount design. Short-circuit protection helps manage speaker faults, and start-up/shutdown pop elimination can improve listening behavior during power transitions. The final design must confirm input gain, speaker impedance, output filtering, EMI behavior, and thermal margins using the manufacturer application information rather than only distributor snippets.
おすすめ
USB Audio Accessory
The MP7752GF can serve as the analog output amplifier stage in a USB audio accessory when the USB interface provides a stereo analog signal. Its analog input and two-channel Class D topology provide a direct path to left and right BTL speaker outputs, while the inductorless design can reduce board area. The verified data does not include USB compatibility, gain settings, input impedance, or EMI limits, so those items must be taken from the datasheet and validated with the complete USB implementation. Pay attention to ground partitioning, cable noise, supply decoupling, and exposed-pad thermal management.
おすすめ
Consumer Audio Amplifier Board
The MP7752GF is appropriate for a compact consumer audio board requiring integrated stereo power amplification and reduced external magnetics. The fixed-frequency inductorless Class D implementation, integrated 240 milliohm MOSFETs, short-circuit protection, and pop-elimination features can simplify the power-amplifier section. The board designer must still plan for the exposed thermal pad, adequate copper and vias, input filtering, output routing, speaker protection, and system grounding. Confirm the exact supply range and load conditions in the manufacturer datasheet because the verified snippets provide only the 18 V and 2 x 15 W headline values.

設計ノート
Treat the exposed pad as the primary thermal path for the MP7752GF. Use the manufacturer land pattern and recommended thermal-via arrangement, then provide as much uninterrupted copper as the PCB area permits. Do not use the 2 x 15 W headline rating as a design allowance by itself; calculate actual dissipation from the selected supply, load, output waveform, efficiency, and ambient temperature. If a thermal estimate is performed, label it as an estimate and state all inputs rather than presenting it as a datasheet limit.
Place input, supply-decoupling, and output components according to the manufacturer reference layout. Keep switching-current loops compact, connect the exposed pad to thermal copper, and route BTL outputs with attention to differential traces and electromagnetic fields. Because the MP7752GF is inductorless, the PCB itself becomes more important for EMI control. Confirm the exact pinout and land-pattern dimensions from the manufacturer datasheet before releasing artwork; the supplied verified data identifies the package but does not provide a complete pin map.
Do not assume that a related ordering suffix is automatically a drop-in replacement. The verified data identifies MP7752GF-P as a related 5 V to 18 V, 2 x 15 W dual-BTL Class-D amplifier, but it does not confirm identical pinout, package construction, or all electrical limits. Before substitution, compare every pin, exposed-pad geometry, supply range, load condition, switching frequency, protection behavior, and thermal limits using manufacturer documentation.
