HM6133 产品概述

一、产品简介

HM6133 是捷茂微(GATEMODE)推出的一款升压型 DC-DC 转换器,采用升压式拓扑并内置开关管,适用于 2.5V 到 5.5V 电源输入场景。器件支持可调输出电压 0.6V 至 30V,最大输出电流可达 3A,开关频率 1.2MHz,静态电流仅 45μA,工作温度范围 -40℃ ~ +85℃,封装为 SOT-23-6。器件为异步整流结构(不带同步整流),面向需高压提升、低静耗与轻载高效的电池供电或汽车电子外围应用。

二、主要规格与性能

  • 输入电压 Vin:2.5V ~ 5.5V
  • 输出电压 Vout:可调 600mV ~ 30V
  • 最大输出电流:3A(受外部元件、散热与输入电压限制)
  • 开关频率:固定 1.2MHz(利于小型电感与滤波器设计)
  • 静态电流 Iq:45μA(空载低功耗)
  • 拓扑:升压式,内置开关管,异步整流
  • 工作温度:-40℃ ~ +85℃
  • 封装:SOT-23-6

三、功能特性与保护

  • 轻载高效模式:在轻载或待机状态下进入高效模式(如 PFM/跳频策略),降低功耗,延长电池寿命。
  • 过流保护(OCP):实时监测开关电流并限制,防止短路或过载损伤。
  • 打嗝限流(Hiccup):在持续短路或严重过载时进入打嗝限流,周期性尝试恢复,以保护器件与外部负载。
  • 启用/关断(EN)与软启动支持(若使用):便于系统控制与降低启动浪涌电流。

四、典型应用场景

  • 便携式设备与电池供电系统:用于从单节或多节锂电池升压到稳压供电,适合便携仪器、手持终端。
  • 工业与汽车外围电子:为传感器、执行器或测量模块提供高压偏置(注意电磁兼容与温度管理)。
  • LED 驱动与小功率功率放大器供电:在可控输出下为 LED 阵列或放大器提供稳定升压电源(依据功率与热设计)。
  • 通用升压模块:USB OTG、备用电源、升压采样电源等场合。

五、外部元件与封装建议

  • 二极管:因为为异步结构,需外接快速肖特基二极管,额定电压应高于目标输出电压,额定电流建议 ≥3A,低正向压降有助于提高效率。
  • 电感:建议选用低 DCR、大电流饱和电流 >Iout 的功率电感,典型值与输出电压、纹波要求相关(常见 1~10μH 范围),高频下可选较小电感以缩小体积。
  • 电容:输入侧选用低 ESR 陶瓷电容以稳定输入并抑制开关噪声;输出侧采用多层陶瓷电容配合必要的并联电解/钽电容以改善负载突变响应。
  • 封装与热管理:SOT-23-6 小封装便于空间受限设计,但需注意功耗与热量导出,建议宽铜地和必要的过孔或散热铜箔。

六、设计注意事项

  • 布局:缩短开关节点(SW)、二极管与电感之间回路,输入电容靠近芯片 VIN 引脚,FB 引脚走线短且远离高频开关噪声。
  • 噪声与滤波:高频开关(1.2MHz)会产生开关噪声,输出滤波与布局对 EMI 有显著影响,必要时增加 RC 滤波或 EMI 抑制措施。
  • 热设计:在高输出电流或高压差工况下,器件功耗增加,需评估板上铜面积与散热通道,避免器件过热触发热保护。
  • 保护与验证:在样机验证阶段覆盖短路、换负载、启动顺序和温度极限测试,验证打嗝限流与过流保护动作是否满足系统需求。

HM6133 以其宽输入范围、高输出电压能力、低静态电流和完整保护特性,适合对体积、低功耗与可控升压有较高要求的应用场合。设计时重视外部器件选型与 PCB 布局,可获得稳定、高效的升压性能。

Sourcing availability signal

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
