R1244N001B-TR-FE 产品概述

一、概述

R1244N001B 是 NISSHINBO 提供的一款基于 CMOS 工艺的降压型 DC/DC 转换器,采用 SOT-23-6W 封装,内置开关管,输出可调。器件工作电压范围宽(4.5V 至 30V),输出电压可在 0.8V 至 15V 之间调整,最高输出电流可达 1.2A,开关频率为 1.25MHz,适合对体积与开关频率有较高要求的点对点电源解决方案。

二、主要特点

  • 输入电压:4.5V ~ 30V
  • 输出电压:0.8V ~ 15V(可调)
  • 输出电流:最大 1.2A
  • 开关频率:1.25MHz(典型)
  • 内置上端开关,典型导通电阻 RDS(on)=0.35Ω
  • 保护功能:逐波(cycle-by-cycle)限流、尖峰电流限制、短路保护、热关断、欠压锁定(UVLO)
  • 工作温度范围:-40℃ ~ +85℃(TA)
  • 封装:SOT-23-6W
  • 拓扑:降压(Buck),单输出通道

三、保护与可靠性说明

R1244N001B 集成了多项保护机制以提升系统可靠性:逐波限流可以限制每个开关周期的电流峰值,短路保护在输出发生硬短时抑制损耗并允许器件恢复;热关断在芯片温度异常上升时自动断开以避免永久损伤;欠压锁定保证在输入太低时不进入不稳定工作状态。这些功能使该器件适合工业与汽车类宽输入电压场景。

四、应用建议与布局要点

  • 外围元件:常见应用中需配合合适的电感、输入/输出低 ESR 陶瓷电容以及必要的反馈分压器。若采用非同步降压结构,系统需外接肖特基续流二极管;若采用同步整流方案可进一步提高效率。
  • 电感与电容选择:根据输出电流与纹波要求选择低 DCR 的功率电感(典型 µH 级范围),输出侧建议使用多颗低 ESR 陶瓷电容以降低纹波并改善瞬态响应。
  • PCB 布局:输入电容应尽量靠近器件 VIN 引脚,开关节点走线最短并避开敏感模拟回路,GND 采用单点回流或铺铜以利散热。注意器件导通电阻与功耗,必要时评估封装热阻并保留足够散热面积。

五、典型应用场景

适合汽车电子(经整流稳压或后级点对点供电)、工业控制模块、便携设备电源管理、LED 驱动前级、点对点降压转换等需要宽输入、紧凑封装与可靠保护的场合。

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
