MEL7136BM5G是南京微盟(MICRONE) 推出的一款单通道外置开关管型LED恒流驱动芯片,专为需要灵活调光、宽电压适应的LED照明场景设计。南京微盟作为国内电源管理芯片领域的主流厂商,该产品凭借小封装、宽温特性及完善的保护功能,可覆盖消费电子、汽车、工业等多领域应用,兼顾性能与成本优势。
芯片核心参数围绕LED驱动的稳定性、灵活性展开,关键指标如下:
2.7V~18V的输入范围覆盖了绝大多数常见电源类型,简化系统设计的同时,可适配便携式设备(锂电池)、车载系统(12V电源)、工业设备(9V适配器)等不同场景,无需额外升压/降压模块。
±5%的恒流精度是LED驱动的核心指标之一:即使输入电压波动或环境温度变化,芯片仍能保持LED电流稳定,避免因电流过高导致的LED早衰,或电流过低导致的亮度不足。
芯片仅提供驱动信号,外置MOS管可根据LED负载需求选择(如大电流或高压LED串),既降低芯片自身功耗,又提升系统功率扩展性。
芯片采用SOT-23-5超小型封装(尺寸约2.9mm×1.6mm×1.1mm),适合小型化产品设计(如便携式LED灯、车载氛围灯)。引脚功能如下(参考官方 datasheet):
引脚编号 功能 说明 1 VIN 输入电压端(接电源正极) 2 GND 接地端 3 CS 电流采样端(接Rcs) 4 DIM 调光控制端(PWM/模拟) 5 DRV 驱动外置MOS管栅极综上,MEL7136BM5G是一款适配性强、可靠性高的LED驱动芯片,可满足多场景下的LED照明需求,是小型化、宽温应用的理想选择。

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.
