XL6012E1是芯龙半导体推出的中功率升压型DC-DC电源芯片,针对工业控制、车载电子、LED驱动等场景设计,核心优势聚焦“宽参数覆盖、简化设计、可靠耐用”三大维度:
输入电压覆盖5V~40V,可兼容车载12V/24V、工业24V电源、锂电池(3.7V~4.2V)等多种供电来源;输出电压最高可达60V(升压拓扑下需高于输入),适配大部分中功率负载的升压需求。
持续输出电流达5A,峰值电流支持更高负载冲击,可驱动LED阵列、小型电机、车载辅助电源等中功率设备,无需并联额外芯片。
开关频率范围144kHz~216kHz,避开音频频段(20Hz~20kHz),降低电磁干扰(EMI);频率可通过外部电阻微调,平衡效率与电感尺寸(高频可减小电感体积,低频可提升效率)。
待机静态电流仅3.5mA,适合电池供电场景(如便携式设备、应急电源),减少待机能量损耗,延长续航时间。
XL6012E1支持升压式、SEPIC、反激式、反相式四种拓扑,覆盖不同电压需求场景:
最常用拓扑,输入电压低于输出(如5V→12V、12V→24V),适用于:
输入电压可高于、等于或低于输出(如锂电池3.7V→5V、9V→12V),适合:
可通过外接变压器实现电气隔离,适用于需要隔离的场景:
输出电压极性与输入相反(如+5V→-5V),适用于:
采用TO-220-5直插封装,散热面积大,适合5A大电流场景;引脚间距合理,易手工焊接或自动化贴装,无需复杂散热片即可满足常规工作温度需求。
以车载12V→24V/5A升压方案为例:
该方案可稳定驱动车载24V设备(如行车记录仪、氛围灯),满足宽温(-40℃~85℃)工作要求。
XL6012E1凭借宽电压范围、大电流输出、多拓扑支持与高可靠性,成为工业、车载、LED驱动等中功率升压场景的高性价比选择,内置开关管进一步简化设计流程,降低开发成本。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
