【应用】国产同步BUCK-BOOST转换器应用于户外太阳能供电,输出电流高达1200mA
某客户户外太阳能供电的无线低功耗产品设计中,采用3.7V可充锂电池输出稳定的3.8V给4G模块和 GNSS芯片供电,因此需要一个升降压芯片来实现。圣邦微(SGMICRO)SGM62112-ADJYTD10G/TR是一款自动模式转换的同步BUCK-BOOST转换器,能够工作在1.8V到5.5V输入,固定可调输出电压为1.2V至5.5V,非常适用于这类电池供电的应用。
升降压信号链简单示意如下:
SGM62112-ADJYTD10G/TR应用在该产品中,还有如下优势:
1、 效率高达96%的空载电流,带负载断开的真正停机功能,结合太阳能电池板的应用,非常环保高效节能;
2、 该器件在高于3.6V的输入电压下支持高达1200mA的输出电流,在高于2.4V的输入电压下支持800mA的输出电流,具有足够强的带载能力;
3、 静态电流小于55μA,适合低功耗产品的应用;
4、 工作温度范围:-40℃~85℃,OTP保护功能,可以满足户外恶劣环境;
5、绿色TDFN-3×3-10L封装,非常小巧,适合紧凑型应用。
综上所述,圣邦微SGM62112-ADJYTD10G/TR非常适用于户外太阳能供电产品。
