RT6160AWSC 产品概述

一、主要特点

RT6160AWSC 是 RICHTEK(立锜)推出的一款低静态电流、高效率的 3A 可调输出升降压开关稳压器,支持同步整流与 I2C 数字控制。器件采用降压-升压拓扑、内置开关管,工作电压范围宽(2.2V 至 5.5V),输出电压可通过寄存器或外部调整设置在 2.025V 至 5.2V,适合在输入电压高于、等于或低于目标电压时都能稳定供电。

二、关键参数

  • 输出类型:可调(通过 I2C 配置)
  • 拓扑结构:降压-升压式(Buck-Boost)
  • 最大输出电流:3A
  • 工作电压 Vin:2.2V ~ 5.5V
  • 输出电压 Vout:2.025V ~ 5.2V
  • 开关频率:2.2MHz(高频设计,可减小外部被动元件体积)
  • 静态电流 Iq:1μA(超低待机功耗,利于电池寿命)
  • 同步整流:是
  • 工作温度:-40℃ ~ +125℃
  • 封装:WLCSP-15B(尺寸 2.3 x 1.4 mm)

三、性能与优势

  • 无缝升降压调节:降压-升压拓扑可在输入电压跨越目标电压时平滑转换,适合单节锂电池等电源电压随放电过程变化的场景。
  • 高效率与低损耗:采用同步整流与高开关频率设计,在中高负载下能保持较高效率;2.2MHz 的开关频率有助于使用更小的电感和更紧凑的布局。
  • 超低静态电流:1μA 的待机电流非常适合长时间待机或低功耗设备,减少电池自放电损耗。
  • 小体积封装:WLCSP-15B(2.3×1.4 mm)适合空间受限的便携设备和可穿戴产品。
  • 数字化控制:I2C 接口提供灵活的输出电压设置、监控与可能的故障上报,便于系统集成与调试。

四、典型应用

  • 单节或多节电池供电设备(可穿戴、蓝牙耳机、智能手表)
  • 电池管理与便携式设备(移动支付终端、手持仪器)
  • 物联网节点与低功耗传感终端
  • 需要在宽输入范围内稳定供电的嵌入式系统

五、设计注意事项与建议

  • 外部电感:选用低 DCR、能承受峰值电流的功率型电感;高开关频率允许使用较小体积电感,但需注意峰值电流与损耗。
  • 输出/输入电容:推荐使用低 ESR 的陶瓷电容以降低纹波并保持环路稳定性;靠近芯片放置输入去耦电容以减小环路面积。
  • PCB 布局:将功率回路走线最短、最宽,开关节点与电感、二极管/电容的连接尽量紧凑;为器件热量散发预留充足铜箔或热沉路径。
  • 热设计:在高电流或高压差应用下注意器件发热,必要时增加 PCB 散热或降低连续输出电流以避免热关断。
  • I2C 接口:在系统设计中规划好地址、上电初始化与保护寄存器设置,以利用数字控制的灵活性。

六、小结

RT6160AWSC 结合了升降压拓扑、3A 输出能力、超低静态电流与 I2C 可编程性,适合对体积、功耗和电池寿命有较高要求的便携与物联网设备。其 2.2MHz 高开关频率和 WLCSP 超小封装为系统级紧凑设计提供了良好方案。设计时应着重功率回路布局与热管理,以充分发挥其高效率与稳定性。

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
