AP64350QSP-13 产品概述

一、概述

AP64350QSP-13 是 DIODES(美台)系列的一款高集成降压型 DC‑DC 转换器,采用单通道降压拓扑、内置开关管,并以 SO‑8EP(带外露散热焊盘)封装提供。器件输入电压范围宽(3.8V~40V),输出电压可调(0.8V~40V),最大输出电流可达 3.5A,适用于需要高密度、低静态功耗和宽输入轨支持的电源设计场合。

二、主要电气参数

  • 功能类型:降压型(Buck)
  • 输入电压 VIN:3.8V ~ 40V
  • 输出电压 VOUT:0.8V ~ 40V(可调)
  • 最大输出电流:3.5A
  • 开关频率:100kHz ~ 2.2MHz(可设置)
  • 静态电流 Iq:22μA(低待机功耗)
  • 工作温度范围:-40℃ ~ +125℃
  • 通道数:单通道
  • 开关管:内置功率开关
  • 封装:SO‑8EP(带外露焊盘,便于散热)

三、产品亮点与适用场景

  • 宽输入电压使其能直接适配 12V、24V 供电轨或电池系统,适用于工业控制、通信设备、电源模块及车载电子(需遵从车规相关验证)。
  • 可调输出覆盖从低电压点(0.8V)到高电压输出,灵活支持 SoC、FPGA、模拟电路及外围模块点对点供电。
  • 低静态电流 22μA 有利于降低待机功耗,适合对静态能耗敏感的系统。
  • 高达 2.2MHz 的工作频率支持更小体积的电感与电容,利于高密度电源设计与小型化布局。

四、封装与热管理建议

SO‑8EP 带外露焊盘(Exposed Pad)便于把器件热量通过 PCB 散出。设计时建议:

  • 在 PCB 底层开辟散热地铜并多过孔连接顶层与内层/底层,增大散热路径。
  • 器件铜盘应按厂方参考设计焊盘尺寸焊接,保证良好热阻。
  • 在高负载或高环境温度下做热仿真或测量,必要时考虑散热片或强制风冷。

五、设计注意事项与布局要点

  • 电感选择:电流额定值需大于 3.5A,考虑峰值电流与饱和特性;值取决于开关频率与纹波目标。
  • 输出电容:建议使用低 ESR 的 X5R/X7R MLCC,减小输出纹波并提高瞬态响应。
  • 输入旁路:VIN 到 GND 处靠近器件放置足够大容量的 MLCC,抑制开关瞬态噪声。
  • 反馈回路:以 0.8V 参考点设计分压(若参考电压为 0.8V),并根据器件要求完成补偿或外部优化,确保环路稳定。
  • EMI 与滤波:高频工作时注意输入输出滤波与走线,尽量缩短信号回流环路,必要时添加差模/共模滤波。
  • 保护与可靠性:在实际应用中关注输出过流、过温与启动行为,参考器件 datasheet 的保护特性与应用电路。

六、总结

AP64350QSP-13 以宽输入、可调高输出范围、内置开关和低静态电流为核心优势,适合要求小体积、高效率、低待机功耗且输入轨宽的点对点电源设计。实际工程应用时,应结合厂方 datasheet 的详细参数(如 RDS(on)、效率曲线、软启动与保护细节)进行元件选型与 PCB 布局,以保证可靠性与最佳性能。若需进一步的电路示例或布局参考,可查阅 DIODES 官方应用手册或索取样品评估板。

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
