MCP16301HT-E/CH 产品概述

一、概述

MCP16301HT-E/CH 是 MICROCHIP(美国微芯)推出的一款高效率、低静态电流单通道降压型 DC-DC 调节器。器件集成功率开关管,工作频率为 500kHz,输入电压范围宽(4.7V 至 36V),输出可调(2V 至 15V),最大输出电流可达 600mA,静态电流仅 7.5µA。封装为 SOT-23-6,适合空间受限且对待机功耗敏感的工业与便携应用。

二、主要参数与特点

  • 输入电压:4.7V ~ 36V
  • 输出电压:2V ~ 15V(可调)
  • 最大输出电流:600mA
  • 开关频率:500kHz(固定)
  • 静态电流(Iq):7.5µA(低待机功耗)
  • 拓扑:降压(同步/非同步取决型号;本型号为内置开关管降压)
  • 封装:SOT-23-6
  • 品牌:MICROCHIP(美国微芯)

三、典型应用场景

  • 工业控制与传感器供电(24V 至 12V 降压)
  • 汽车电子边缘电源(工作温度宽 -40℃~+125℃)
  • 可穿戴与便携设备的节能供电
  • 仪表、通信设备和备用电源模块

四、设计与选型要点

  • 稳定性与纹波:建议输出端采用低 ESR 陶瓷电容配合适量电解/钽电容以降低纹波并增强瞬态响应(典型组合:陶瓷 10µF47µF + 22µF100µF 电解/钽)。
  • 电感选择:根据开关频率和允许的电流纹波 ΔIL 计算电感,常用公式:L = (Vin - Vout) * D / (ΔI * fsw),其中 D = Vout/Vin,fsw = 500kHz。例如 Vin=12V、Vout=5V、目标 ΔI≈0.3A 时,估算 L ≈ 19µH。实际选型须考虑峰值电流、饱和电流和损耗。
  • 反馈与补偿:采用厂家推荐的反馈电阻网络与布局,保证环路稳定性并满足精度要求。
  • 保护与可靠性:器件集成开关管和低功耗特性,设计时请参考 datasheet 验证短路保护、热关断和启动/关断行为以满足系统可靠性需求。

五、PCB 布局与散热建议

  • 开关节点(SW)与输入电容、功率电感之间走线应尽量短且宽,减小辐射与寄生电感。
  • 输入电容尽量靠近 VIN 与 GND 引脚放置,反馈网络靠近 FB 引脚布置以减少噪声干扰。
  • 虽为 SOT-23-6 小封装,但在高输入/高输出差或接近 600mA 工作时注意散热:增大铜箔面、必要时加散热过孔并保持良好接地。
  • 在汽车或工业场景下建议增加输入滤波和瞬态抑制器以提高抗干扰能力。

六、封装与订购信息

  • 封装:SOT-23-6,适合小尺寸 PCB 布局。
  • 型号:MCP16301HT-E/CH(具体批次、打标与封装形式请以 MICROCHIP 官方资料及销售描述为准)。
  • 选型提示:在最终电路设计前,请下载并详细阅读官方 datasheet、典型应用示例和评估板资料,进行仿真与样机验证,确保满足温度、效率与电磁兼容等系统级要求。

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
