MP2460GJ-Z 产品概述

一. 产品简介

MP2460GJ-Z 是 MPS 推出的降压型同步整流 DC-DC 开关稳压器,采用 TSOT-23-6 小封装,内置开关管,针对空间受限且需高效降压的应用场景设计。器件支持宽输入电压范围与可调输出,适合多种工业与消费类电源设计。

二. 主要规格

  • 功能类型:降压型(Buck)
  • 输入电压范围:4.5V ~ 45V
  • 输出电压范围:800mV ~ 44.1V(可调)
  • 输出电流:最大 600mA
  • 开关频率:约 1.7MHz
  • 静态电流(Iq):典型 150µA
  • 同步整流:支持(内部同步开关)
  • 开关管:内置
  • 输出通道数:单路
  • 工作温度:-40℃ ~ +125℃(结温)
  • 封装:TSOT-23-6

三. 关键特性与优势

  • 宽输入电压覆盖 4.5V–45V,能够直接支持 5V/12V/24V 等电源轨,适用于多种电源总线。
  • 1.7MHz 高开关频率,有利于使用更小体积的电感与输出电容,利于紧凑布局与尺寸受限的应用。
  • 内置同步整流与开关管,简化外部元件数量,提高转换效率并降低系统成本。
  • 低静态电流(150µA),在轻载或待机模式下能降低系统功耗,适合功耗敏感设计。
  • 宽输出可调范围(0.8V 起),可用于生成多种点到点电压要求。

四. 典型应用

  • 工业控制与通信设备的点到点电源
  • 车载电子(适用于 12V/24V 总线场景,需注意系统合规性)
  • 仪器仪表与供电模块
  • 便携与消费类电子需要高密度电源的场合
  • LED 驱动与电池供电系统的降压部分

五. 设计与布局建议

  • 输出电压设定:采用反馈分压器,参考反馈电压 VFB=0.8V,VOUT = VFB × (1 + R1/R2)。
  • 电感选择:根据输出电流 600mA 与峰值电流裕量选择合适电感,注意电感的饱和电流与 DCR 影响效率。
  • 电容选型:输入侧选用低 ESR 的陶瓷电容以抑制尖峰与提高稳定性;输出侧推荐低 ESR 陶瓷以降低纹波。
  • 布局要点:SW 节点走线尽量短且与敏感信号隔离,VIN 与 GND 电容靠近器件引脚,反馈网络布局要远离开关噪声源,保证调节精度。
  • 热管理:TSOT-23-6 封装散热能力有限,高功率损耗下需通过铜箔铜面积扩散热量,必要时在 PCB 下方增加散热铜箔或过孔。

六. 注意事项

  • 虽然器件支持高达 45V 输入,应在具体系统中考虑瞬态抑制与输入滤波,必要时加入 TVS 或串联限流元件。
  • 设计中预留安全裕量,选择元件(电感、电容、肖特基/二极管若外置)需满足最大工作电流与温度要求。
  • 若用于车载或高可靠性场合,请结合系统级认证与 EMC 要求做进一步验证。

MP2460GJ-Z 以其宽输入、可调输出、高开关频率和小封装特性,为需要高密度、节能的降压场景提供了实用的解决方案。

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.

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
