MP7770GF-Z 产品概述
一、产品简介
MP7770GF-Z 是 MPS 推出的一款高效 D 类音频功率放大器，提供单声道（1 通道，桥接输出）或双声道（2 通道，立体声）配置，封装为 28‑TSSOP‑EP。器件工作电压范围宽（9.5V 至 36V），适用于车载音响、便携音箱、家庭音频及主动低音炮等对效率与体积要求较高的应用。
二、关键电气参数
- 输出功率：108W ×1 @6Ω（桥接单声道），41W ×2 @4Ω（立体声工作）
- 总谐波失真 + 噪声（THD+N）：0.03%（典型）
- 静态电流（Iq）：3mA（低待机功耗）
- 电源纹波抑制比（PSRR）：-60dB（优秀的电源噪声抑制）
- 工作效率：最高可达 95%，典型工作模式下 90% 与 91% 等值
- 工作温度范围：-40℃ 至 +125℃
三、功能特性
- 自动静音 / 免噪音开关（pop‑free mute），减少开关瞬态噪音
- 过压保护，提升系统可靠性并便于车载或工业电源使用
- 可配置输出拓扑，支持桥接单声道或双通道立体声灵活切换
- 低静态功耗，适合对待机能耗敏感的系统
四、封装与热管理
封装形式为 28‑TSSOP‑EP，带底部散热焊盘（EP），建议 PCB 布局时：
- 在焊盘下方及周围使用多层大铜箔散热通道并与器件底部焊盘良好焊接
- 靠近电源引脚放置足够的去耦电容（低 ESR）；为保证 -60dB PSRR 与高效率运行，输入端建议并联陶瓷与薄膜电容
- 在高功率输出场景下注意热限流与外部散热器，必要时进行降额设计以保证在 +125℃ 环境下长期可靠
五、典型应用场景
- 汽车音响与娱乐系统（需宽电压和过压保护）
- 便携式蓝牙音箱与家庭音频放大模块
- 主动式低音炮与多声道合并放大器设计
- 工业音频提示与公共广播系统
总结：MP7770GF-Z 集成高效率、低失真与完整保护特性，适合对功率密度与电源兼容性要求高的音频系统，灵活的输出拓扑与低待机电流使其在车载与消费类产品中具有较高的设计价值。若需具体电路图、典型应用原理图或 PCB 布局建议，可基于目标负载与散热条件进一步提供参考设计。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
