K7803-1000R3 产品概述

一、产品简介

K7803-1000R3 是 YLPTEC(易川) 出品的一款降压型开关稳压器,输出单通道 3.3V,最大输出电流 1A,适用于输入电压范围较宽的电源方案。器件封装为 SIP 封装(11.5×7.6mm),体积小巧,便于模块化设计和密集布板。

二、主要性能参数

  • 功能类型:降压型(Buck)
  • 输入电压 Vin:6V~36V
  • 输出电压 Vout:3.3V(固定)
  • 最大输出电流:1A
  • 转换效率:典型 90%
  • 开关频率:500kHz
  • 纹波噪声:60mVp-p(典型)
  • 最大容性负载:680μF

三、特点与保护

  • 内置短路保护,提升系统可靠性与安全性;
  • 高效率设计,减小功耗与发热,利于电池供电与高密度应用;
  • 宽输入范围适配12V/24V等常见母线;
  • 500kHz 高频可使外部电感、电容体积进一步优化。

四、机械与环境指标

  • 尺寸(长×宽×高):11.5mm × 7.55mm × 10.2mm(参考)
  • 封装:SIP,11.5×7.6mm
  • 工作温度:-40℃ ~ +85℃

五、典型应用场景

适用于工业控制、电源模块、通信设备边缘电源、物联网终端、仪器仪表及其他需将较高直流电压降至稳定 3.3V 的场合。

六、使用建议与注意事项

  • 为保证稳定性与抑制纹波,建议在输入侧并联适当低 ESR 电解或钽电容,输出侧配合 680μF 以下的电容并遵循厂商推荐等效等容配置;
  • 高频开关工作需注意布局,输入、开关节点与输出电容尽量靠近器件引脚,减小环路面积以降低 EMI;
  • 在高温或靠近额定极限输出时建议进行电流和温升裕度评估并适当降载;
  • 短路保护为重要安全特性,但长期短路仍应避免,应在系统设计中考虑故障隔离与告警。

七、封装与采购信息

品牌:YLPTEC(易川);型号:K7803-1000R3。封装小巧、通过校验,便于批量装配与模块化替换。具体样片、典型电路图与器件手册请向供应商索取以获得完整的外形尺寸、引脚定义与应用参考。

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
