概览

随着消费者越来越喜欢无线耳机的便利性、便携性和更好的用户体验，全球无线耳机市场正在显著增长。 这一趋势推动了对具有更长的电池寿命的产品的需求，以支持更长的使用时间，而无需频繁充电。

该设计的特点是无线耳机和充电座采用了超低功耗的 48MHz Arm® Cortex®-M23 MCU，以及同类最佳的高效电源系统，从而延长了电池使用寿命。

系统优势：

  • 高级安全性、连接性和软件灵活性
  • 集成模拟前端（AFE）减少了多个模拟组件，降低了 BOM 成本和 PCB 尺寸
  • 紧凑型设计，适用于空间有限的应用
  • 高效的低静态电流电源系统，带有电压监控器和降压稳压器，可延长电池寿命

应用

  • 无线耳机
