CH224A 产品概述
一、产品简介
CH224A 是南京沁恒（WCH）推出的一款受电控制器，面向需要接收并稳压多档输出电压的电力电子系统。器件输出功率可达 140W，支持常见直流输出档位，适配对功率密度和温度适应性有较高要求的应用场景。封装为紧凑型 ESSOP-10，便于高密度 PCB 布局与系统集成。
二、主要性能与关键参数
- 类型：受电控制器
- 最大输出功率：140W
- 支持输出电压（常用档位）：5V、9V、12V、15V、20V、28V
- 工作温度范围：-40℃ ~ +105℃
- 品牌：WCH（南京沁恒）
- 封装：ESSOP-10
以上参数表明 CH224A 适用于需要多档稳压输出且总功率较大的受电场景，可在较宽温度范围内稳定工作，满足工业级应用温度需求。
三、封装与热管理
CH224A 采用 ESSOP-10 紧凑封装，便于在受限空间内实现模块化设计。为保证长期可靠性与稳定输出，推荐在 PCB 设计中：
- 为器件引脚和散热区域预留足够的铜箔面积以增强热扩散；
- 在输出端与电源端配置合适的去耦与滤波电容，靠近器件布局以降低寄生电感；
- 考虑器件在高温工况下的降额使用，必要时增加散热片或风冷。
四、典型应用场景
CH224A 适配于多种需受电并生成多档稳压输出的应用，例如：
- USB PD/受电端模块与便携式快充方案；
- 大功率移动电源与充电仓；
- 车载充电与车载电子供电模块；
- 工业控制电源与现场设备供电模块。
五、设计与使用建议
- 系统级保护：建议在方案中配合过流、过压、短路及过温保护措施（例如熔断器、限流电路或外部保护 IC），以提升系统安全性；
- 布局建议：输入与输出的电容应尽量靠近器件引脚布置，保持良好接地回路以减少环路面积与 EMI；
- 环境适应：在高温或高功率连续输出工况下，应注意热量管理与元件老化，必要时进行长期可靠性测试。
CH224A 以其 140W 的输出能力、丰富的电压档位和宽温度范围，适合要求稳定供电与高集成度的中高功率受电应用。如需详细电气参数、引脚定义或典型应用电路图，可提供进一步资料和设计支持。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
