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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
