MP4248GQV-0000-Z 产品概述
一、概述
MP4248GQV-0000-Z 是一款面向高功率点负载的降压-升压型开关稳压器，支持 3.6V 至 36V 宽输入，输出可调 1V 至 36V，最大输出电流 7A，系统最高功率可达 140W。器件采用降压-升压拓扑并集成低侧功率 MOSFET，支持高侧电流测量和 I2C 接口，用于监控与配置，适合电池供电与车载/工业电源等需要跨电压工作点的场景。
二、主要特性
- 输入电压范围：3.6V ~ 36V
- 输出电压范围：1V ~ 36V（可调）
- 最大输出电流：7A，系统功率至 140W
- 开关频率：提供 280kHz、420kHz、580kHz 三档典型选项（具体选择方式见器件手册）
- 静态电流（Iq）：约 775μA，支持轻载高效模式以降低待机功耗
- 同步整流：支持，内置低侧 MOSFET（降低外部元件复杂度）
- 内置 LDO 稳压器，为内部偏置或外部参考提供稳定电源
- 保护与控制：过流保护、可调限流、打嗝限流、输出放电、工作状态指示（支持通过 I2C 读取/配置）
三、功能亮点
- 降压-升压转换能力，输入电压可高于或低于目标输出，适应电池放电曲线或系统电压波动。
- 低静态电流结合轻载高效工作模式，适合需长待机或低静态损耗的便携与远程设备。
- I2C 接口增强系统集成，支持运行状态监测、故障报告与部分参数配置（详见数据手册）。
- 支持高侧电流感测，便于实现精确限流和功率管理策略。
四、封装与环境条件
- 封装：QFN-20 (3x5 mm)，便于表面贴装与热量散逸。
- 工作结温范围：-40°C ~ +125°C (TJ)，适应宽温度工业级应用。
- 推荐 PCB 设计采用露热焊盘和充足铜箔用于散热，电源回路宽短设计以降低寄生阻抗。
五、典型应用
- 汽车及车载电子（辅助电源、车载信息娱乐）
- 电池供电系统与便携设备（要求跨升降压的电源管理）
- 工业控制与通信设备的点负载稳压器
- 需精准限流或远程监控的功率模块
六、设计注意事项
- 输入与输出端应靠近器件放置低 ESR 电容以抑制纹波并保证稳定性。
- 高侧电流感测需要合适的电阻布局与滤波，参考器件手册中的检测与校准建议。
- 为发挥 140W 能力，PCB 热设计（热沉铜、焊盘）和散热路径需充分考虑。
- 开关频率选择在效率、元件尺寸与 EMI 间权衡，具体参数与布局请参照参考设计与评估板。
MP4248GQV-0000-Z 在高功率密度与灵活电压适应性方面具有优势，适合需要稳健限流与系统监控能力的中高端电源设计。欲了解详细引脚、寄存器、参考电路与布局指导，请参阅官方数据手册与评估板资料。

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.
