LM1501BGR-ADJ 降压型DC-DC转换器产品概述

LM1501BGR-ADJ是HTC品牌推出的一款非同步降压型DC-DC转换器,专为中高压输入、宽范围可调输出的电源场景设计,具备宽温工作、内置开关管等核心特点,适配工业、通信等多领域的中等功率供电需求。

一、核心功能与拓扑设计

该器件采用降压式(Buck)拓扑,属于非同步整流架构(无内置续流管,需外置续流二极管),核心功能为将较高电压输入转换为稳定的低压或近高压输出。其内置高压功率开关管,无需额外外置MOSFET,可直接简化电路BOM与设计复杂度;输出电压支持连续可调(1.23V~37V),覆盖从低压逻辑电路(1.2V级)到接近输入电压的降压范围,适配不同负载的灵活电压需求。

二、关键电气参数解析

1. 输入输出宽范围覆盖

  • 输入电压:支持最高40V直流输入,兼容24V/36V工业电源、12V/24V车载电源等常见中高压供电场景;
  • 输出电压:1.23V(内置基准电压)至37V连续可调,无需更换器件即可适配从低压MCU到高压模拟电路的多种负载;
  • 输出电流:额定5A连续输出,可满足小型电机、通信模块、工业传感器等中等功率负载的供电需求。

2. 效率与控制特性

  • 开关频率:固定300kHz,处于中等频率区间——既避免了高频(>1MHz)带来的EMI干扰与元件选型难度,又无需低频(<100kHz)所需的大体积电感电容,平衡了性能与成本;
  • 静态电流(Iq):5mA,在非同步降压器件中表现适中,适合需要轻载待机效率的应用(如设备待机时仍需维持输出的场景);
  • 内置开关管:耐压与电流能力匹配5A输出需求,减少了外置功率器件的选型、散热设计及布局空间占用。

3. 宽温工作可靠性

  • 工作温度范围:-40℃~+125℃,符合工业级器件标准,可在户外设备、高温车间等极端环境中稳定运行,无需额外散热补偿或降额使用。

三、封装与引脚配置

LM1501BGR-ADJ采用TO-263-5贴片封装,引脚数为5,布局紧凑,适合PCB自动化生产与高密度电路设计。TO-263封装具备一定的散热能力,可通过PCB铜箔扩展散热面积,满足5A输出的热管理需求(需注意负载电流与环境温度的匹配,避免长期过热)。

四、典型应用场景

  1. 工业电源系统:PLC模块供电、工业传感器电源、小型工业控制器等(兼容24V/36V工业输入,宽温适应车间环境);
  2. 通信设备:基站分布式电源、光纤收发器供电、小型通信模块等(宽输出范围适配不同芯片电压,5A电流满足多负载需求);
  3. 车载电子:部分低压车载系统(如12V/24V输入)的辅助电源、车载显示屏供电等(需注意车载电磁兼容要求);
  4. 测试测量设备:可编程电源模块、负载测试设备等(可调输出满足不同测试电压的动态需求)。

五、核心优势总结

LM1501BGR-ADJ的核心优势可概括为:

  • 宽范围适配:40V输入→1.23V~37V输出,覆盖90%以上中等功率降压场景;
  • 设计简化:内置开关管+TO-263封装,减少元件数与PCB空间;
  • 工业级可靠:-40~125℃宽温,满足极端环境应用;
  • 灵活可调:连续输出电压调整,适配多负载电压需求。

该器件适合对成本敏感、需要宽电压范围与宽温工作的中等功率降压应用,是工业、通信等领域电源设计的实用选择。

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
