【应用】超低静态电流DC电源芯片SGM6021等配合贴片功率电感助力锂亚电池供电IoT产品设计

时间： 2020-09-15 来源：世强

采用一次性锂亚电池供电物联网IoT产品设计中，通常需要使用一颗DC电源芯片将锂亚电池输出的3.6V电源降压后给MCU和射频芯片部分供电。对应电池供电的IoT产品在选型DC芯片时，通常需要DC芯片具有非常低的静态电流并且在轻载时候有很高的电源转换效率，推荐使用圣邦微的SGM6021/SGM6031/SGM6036系列DC进行设计，三颗物料部分参数对比如下表。

从上表可以看出，SGM6021/ SGM6031/SGM6036最低输入电压都为1.8V，通常锂亚电池的放电截止电压为2V，SGM6021/ SGM6031/SGM6036可在电池整个放电电压区间工作；nA级的静态电流和轻载模式下非常高的电源转换效率，有助于降低系统整体功耗并延长电池使用寿命。如下图为SGM6036的电源转换效率图，即使在最大5.5V输入电压情况下，10uA负载情况下也可以实现接近80%电源转换效率。在锂亚电池3.6V输入电压情况下，效率更高。

SGM6021/ SGM6031/SGM6036除SGM6021为只有可调电压输出版本外，SGM6031和SGM6036都具备多种固定电压输出和可调电压输出版本可供灵活选择。如下图为SGM6036的固定电压输出版本和可调电压输出版本典型应用电路，在此推荐功率电感L选用麦捷科技的MPIT252010系列小封装贴片功率电感，非常适合小尺寸的IoT产品选用。

MPIT252010系列功率电感主要性能参数如下表，在10uH以下DC-DC转换常用功率电感值都具备小于1Ω的直流电阻，可有效降低功率电感上热量产生，以减少不必要的电池能量消耗。并且在2520封装情况下，饱和电流、温升电流表现也非常出色，可满足大部分IoT产品电流需求。
