MC34063M/TR 产品概述

一、概述

MC34063M/TR 是一款通用型 DC-DC 开关稳压控制器,适用于升压、降压与反相三种拓扑结构。芯片集成开关管与控制电路,支持外部元件实现可调输出,适配广泛电源转换需求。常见封装为 SOP-8(TR 表示卷盘包装),由 HGSEMI(华冠) 生产或代工供应。

二、主要规格(典型)

  • 工作电压范围:3V ~ 40V(允许在高电压工况下工作)
  • 开关管最大峰值电流:约 1.5A(内部开关管)
  • 典型开关频率:约 33kHz ~ 42kHz(由内部振荡器与外部定时电容决定)
  • 工作温度:-40℃ ~ +85℃
  • 输出类型:可调输出电压,支持升压/降压/反相拓扑

(用户资料中亦有 100kHz 的描述,实际频率受外部定时电容与电路布局影响,应以芯片数据手册与实验为准。)

三、功能特点

  • 内置开关管,简化外部功率级设计与焊接工艺;
  • 支持三种常用拓扑:降压(buck)、升压(boost)、反相(inverting);
  • 输出电压可通过简单的电阻分压+外接电感、肖特基二极管与电容实现精调;
  • 小封装(SOP-8)适合中小功率模块化设计与批量生产。

四、典型应用场景

  • 便携式设备电源升压/降压模块;
  • 单节电池到系统电压的转换(如 1 节锂电升压至工作电压);
  • 工业控制与通信设备的本地电源管理;
  • 负电压产生(反相电源)和隔离前级电源。

五、设计注意事项

  • 输入与输出电容要选低 ESR、耐压合适的电解或固态电容以降低纹波与稳定环路;
  • 电感和肖特基二极管需根据开关电流与峰值电流余量选择,注意散热与饱和电流;
  • 封装功率耗散受 PCB 铜箔面积与散热条件限制,高电流或高 Vin 情况下需加强散热;
  • 布局建议:输入滤波、电感与肖特基二极管尽量靠近芯片,回流路径短且粗;
  • 保护与稳定:可加入软启动、限流与过温保护电路,防止芯片在异常工况下损坏。

六、封装与采购信息

  • 常见封装:SOP-8,TR 表示卷盘包装,便于贴片生产线使用;
  • 推荐在工程验证阶段参考完整数据手册与典型应用电路,按实际使用工况选型与可靠性验证。

MC34063M/TR 以其简单的外围器件、灵活的拓扑支持和宽电压范围,适合需要低成本、可调输出的中低功率开关电源场合。但在高效率或高频率严苛应用时,应评估其频率、开关损耗与热特性是否满足需求。

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
