HT7463C 是 HOLTEK(台湾合泰/盛群)面向中高压场合的降压型开关稳压器(Buck),采用降压拓扑、内置开关管且为非同步整流结构。器件工作电压范围宽(4.5V~60V),输出电流可达600mA,内部振荡频率为1.25MHz,静态工作电流仅约500µA,工作温度范围 -40℃~+85℃,单通道可调输出,封装为 SOT-23-6,适合空间受限且需承受较高输入电压的电源设计场景。
HT7463C 为非同步降压,外部元件的选择对性能影响较大。典型外部元件包括:输入电容、续流二极管(Schottky 或快速恢复二极管)、功率电感、输出电容、反馈分压电阻及使能/软起动元件(若需要)。
总结:HT7463C 适用于需要从高压轨降压到中低电压并且追求小尺寸与较低静态功耗的应用。在选型与电路设计时,重点关注续流二极管的耐压与低 Vf、合适的高频小体积电感以及良好的 PCB 布局与热管理,以确保系统在目标工作点下的效率与可靠性。

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.
