XL9023 是一款同步整流、降压型(Buck)开关稳压器,集成高侧与低侧功率开关,适用于宽输入电压范围的降压稳压应用。器件支持输入电压 5V~40V,输出可调 1.25V~35V,最大输出电流 4A,典型开关频率约 120kHz(范围 96kHz~144kHz),工作温度范围 -40℃~+125℃。封装为 TO-252-5L,适合中功率、高密度的电源方案。
XL9023 适用于车载、工业控制、通信设备、仪器仪表、分布式电源及各种需要从较高电压降压到中低压并且需高效率和小尺寸的场合。典型应用包括:
设计时需注意:在高 Vin、接近最大输出电流工作时,开关和导通损耗都会显著增大,需良好散热(大面积铜箔、连接散热片或使用热沉)以保证器件在安全温升内工作。
XL9023 为 5 引脚 TO-252-5L 封装(具体引脚排列以器件数据手册为准),常见引脚功能包括:
具体引脚名称与功能请以正式数据手册为准,设计时应严格按照芯片手册的引脚定义与电气参数。
结语:XL9023 面向需在宽输入电压下输出可调中低压并要求较高效率与中等开关频率的单路降压应用,内置同步开关与过流保护,TO-252-5L 封装便于实现紧凑且具有良好散热的电源模块设计。请在最终设计与量产前参照 XLSEMI 官方数据手册和参考设计进行详细验证。

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.
