【选型】SGMICRO升降压转换器SGM62110用于TWS耳机，静态电流仅18μA

时间： 2022-08-01 来源：世强

技术问答

面对如今逐渐多元化的消费类电子产品，其在功能及外形上也更加丰富。其中TWS耳机也是一大热点，在小型化上要求越来越高，因此产品的功率密度、效率、功耗等指标上是新的挑战。本文从性能参数及封装尺寸等方面分析，讨论圣邦微电子（SGMICRO）升降压转换器 SGM62110在TWS耳机上应用的优势。

SGM62110典型应用如下：

图1 SGM62110典型应用

SGM62110主要参数

表1 SGM62110 主要参数特性

SGM62110输入工作电压范围2.2V~5.5V，满足大多数电池供电的小型化设备的输入范围；在3.3V输出，10mA至2.5A负载段时可达到超过90%转换效率；静态电流18μA，在低功耗的应用上颇具优势；内置输入输出过压、过流、短路、过温保护，WLCSP-2.21×1.40-15B小封装有利于PCB设计上的布局，更省空间。

综上所述，SGM62110应用于TWS蓝牙耳机时，在适用范围，功耗以及设计布局上具备一定优势。
