MPQ4572GQB-AEC1-Z 是 MPS 推出的汽车级降压型 DC-DC 转换器,单通道可调输出,输入电压范围宽:4.5V 至 60V,输出可调 1V 至 54V,持续输出电流最高 2A。器件内置功率开关并采用同步整流拓扑,开关频率 2.2MHz,静态电流仅 40µA,工作结温范围宽:-40℃ 至 +150℃(TJ)。封装为 QFN-12(2.5 × 3 mm),适合空间受限的高可靠性应用。
适用于汽车电子(车载域控制器、摄像头、信息娱乐)、工业控制与仪器、分布式电源点负载、通信设备辅助电源及需要宽输入/高可靠性的电源模块。
高频率 2.2MHz 可显著减小电感与输出电容尺寸,利于紧凑布局;同步整流提高效率并减少散热;低 Iq 与轻载高效模式在待机/休眠状态下可降低系统功耗;内置开关降低 BOM 与布局难度。宽输入支持常见汽车负载跌落与浪涌,但需在实际系统中验证抗瞬态能力和输入滤波设计。
该器件适合对尺寸、效率与宽输入要求较高的汽车与工业场景。选型时注意评估系统峰值电流、输入瞬态、散热能力及 EMI 要求;对关键应用建议参考完整 datasheet 与实际板级测试(热仿真、效率曲线、瞬态响应与保护触发条件)。
总结:MPQ4572GQB-AEC1-Z 提供宽输入、高开关频率、低静态功耗与完善保护的单通道可调降压方案,适合空间受限且需兼顾效率与汽车级可靠性的电源设计。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
