MP2386GG-Z 产品概述

一、产品简介

MP2386GG-Z 是美格芯(MPS)推出的一款高集成度降压型 DC-DC 转换器,封装为 QFN-11 (2x2)。器件集成同步整流开关管,工作电压范围宽(4.5V~24V),输出电压可调(600mV~13V),最高输出电流可达 8A,开关频率为 700kHz,适用于点对点电源、板载电源和多种工业/消费类电子应用。

二、主要参数与特性

  • 输入电压 Vin:4.5V ~ 24V
  • 输出电压 Vout:600mV ~ 13V(可调)
  • 输出电流 Iout:最高 8A(内置功率开关)
  • 开关频率:700kHz(固定)
  • 静态电流 Iq:约 105µA(轻载节能)
  • 封装:QFN-11 (2x2)
  • 同步整流:内置同步 MOSFET,提高轻载与满载效率
  • 保护与控制:逐波限流、过流保护、打嗝限流、保护锁死、输出放电、工作状态指示
  • 控制方式:支持外部补偿以优化闭环稳定性与瞬态响应;提供轻载高效工作模式

三、功能亮点与应用价值

  • 轻载高效:低静态电流设计配合高效同步整流,在轻载或待机工况下能显著降低系统待机功耗。
  • 可调输出与外部补偿:输出电压范围宽,支持通过外部反馈与补偿网络精确设定环路带宽与相位裕度,便于按系统要求优化瞬态响应与稳定性。
  • 多重保护:器件内建逐波限流与过流保护,并具备打嗝限流与保护锁死策略,兼顾短路响应与异常恢复能力;输出放电功能可在关闭或故障时快速释放输出残余能量。
  • 高频开关:700kHz 工作频率有利于减少电感与输出电容尺寸,为空间受限的应用提供更紧凑的电源解决方案。

四、封装与热管理

QFN-11 (2x2) 小尺寸封装适合空间受限板级电源。由于输出电流可达 8A,热量管理至关重要:建议在 PCB 上使用足够的散热铜箔与过孔连通底部裸露焊盘(exposed pad),优化热阻;合理选择电感与 MOSFET 导通损耗,测试在最大负载与高 ambient 温度下的结温表现,确保器件工作在 -40℃ ~ +125℃ (TJ) 范围内。

五、典型应用场景

  • 点对点(PoL)板载电源,为 SoC、FPGA、ASIC 等供电
  • 工业控制与嵌入式系统的主/辅电源供应
  • 电池供电设备与便携式电子产品(需配合输入瞬态保护)
  • 通信设备、消费电子与汽车电子(非直接宣称汽车级,需按系统要求做瞬态与抗扰度设计)

六、设计注意事项

  • 布局:输入电容应尽量靠近器件供电引脚,功率回路(开关节点、输入/输出电容、器件)回路面积要最小化以降低 EMI。
  • 电感选择:按峰值电流、纹波允许范围与饱和特点选型,尽量选低 DCR 以降低损耗并改善热性能。
  • 输出电容与 ESR:与外部补偿网络一起决定环路稳定性与瞬态响应,调试时参考器件参考设计与典型应用电路。
  • 保护与测试:验证逐波限流、打嗝限流与保护锁死在各种异常工况下的行为;做热滥用、短路与过温测试以确认系统可靠性。

总结:MP2386GG-Z 是一款面向中高电流、空间受限且需高效率与丰富保护功能的降压转换器。其宽输入、可调输出与外部补偿特性,使得在不同负载与系统要求下都能实现良好的能效与稳定性。欲获得完整电气性能、典型应用原理图与布局建议,请参阅官方数据手册与参考设计。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
