R-78E12-0.5 产品概述

一、产品简介

R-78E12-0.5 是 YLPTEC(易川)推出的一款工业级升降压型双路直流-直流转换模块,采用标准 SIP-3 封装,适用于要求宽输入电压、稳定 ±12V 双轨电源的小型化系统。模块工作温度范围宽(-40℃ 至 +85℃)、静态电流低,内置保护功能,适配工业电力、工控、通信与轨道交通等场景。

二、主要参数

  • 功能类型:升降压型(Buck-Boost)双路输出
  • 输入电压(可选/典型):8V~24V 或 15V~36V(视具体型号或应用连接)
  • 输出通道数:2(含支持负输出)
  • 输出电压:+12V 和 -12V
  • 输出电流(最大):+12V 通道 500mA;-12V 通道 -150mA
  • 输出电压精度:±3%
  • 转换效率:典型 94%~95%;在部分输入/轻载条件下最低可达约 85%
  • 静态电流:200µA(无载空载功耗低)
  • 纹波噪声:20mV p-p(典型)
  • 开关频率:850kHz
  • 最大容性负载:680µF / 330µF(两路分别允许的最大容性负载,具体见样本)
  • 工作温度:-40℃ ~ +85℃
  • 机械尺寸:11.5mm × 7.55mm × 10.2mm(SIP-3 封装)
  • 保护特性:短路保护,自动故障恢复

三、功能特性

  • 升降压能力:在输入电压低于或高于目标输出时均能稳定保持 ±12V 输出,适合电池供电、车载和不稳定电源环境。
  • 低待机功耗:200µA 的静态电流有利于低功耗或备用电源应用,延长电池寿命。
  • 高频开关:850kHz 工作频率使得外部磁性与电容件体积可最小化,利于系统小型化。
  • 保护与可靠性:自恢复短路保护避免长时间故障损坏,可在消除短路后自动恢复供电,提高系统可靠性。
  • 支持负轨输出:内置负电压通道,便于运放、信号调理等需要对称电源的电路设计。

四、典型应用场景

  • 工业自动化与控制柜:为传感器前端、隔离放大器、模拟输入模块提供 ±12V 电源。
  • 工业通信设备与物联网节点:在电源波动或远端供电场景提供稳定双轨电源。
  • 汽车电子与轨道交通:宽输入、耐温性能适合车载或车载周边电子模块(需注意车规级 EMC 要求)。
  • 仪器仪表:便捷为运放、AD/DA 前端等供给对称电源,减小系统占位空间。

五、设计与安装建议

  • 输入滤波:建议靠近模块输入端布置低ESR电解或固态电容与陶瓷旁路电容,以降低输入纹波与抑制共模干扰。
  • 输出电容:根据负载与纹波要求选择合适电容,注意模块标注的最大容性负载限制,超额可能造成启动或稳定性问题。
  • 散热与布局:尽管效率高,但在满载时仍有热量产生,应保证周围气流与可用铜箔散热区域,避免长期在高温工况运行。
  • 接地与走线:信号地与功率地分区布线,输入/输出走线尽量短且粗,以减小寄生电感并降低 EMI。
  • EMC 考量:在对电磁兼容有严格要求的应用中,增加输入侧共模电感、Y 电容以及输出端滤波有助于通过辐射与传导测试。

六、选型与注意事项

  • 确认输入工作范围:根据实际系统电源(电池、车载、配电)选择 8–24V 型或 15–36V 型,避免超出模块允许范围。
  • 负载裕度:长期满载会增加温升,建议留有余量(例如选择至少 20% 的电流裕量)以提高可靠性。
  • 环境条件:高温或高振动场合需评估模块长期漂移与焊接可靠性,必要时做环境应力测试。
  • 轨间耦合与启动序列:双路输出在特定负载或启动顺序下可能互相影响,需在系统层面验证启动稳定性。

七、封装与订购信息

  • 品牌:YLPTEC(易川)
  • 型号:R-78E12-0.5
  • 封装:工业标准 SIP(SIP-3),便于插入式或插件化设计
  • 典型外形尺寸:11.5 × 7.55 × 10.2 mm
  • 适用领域:电力、工控、通信、物联网、汽车、轨道交通等

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
