【应用】超低功耗型低压DC-DC OC6811为传统遥控器两节电池提供单节电池供电解决方案
遥控器是家用电器如空调,电视,电视盒子等设备必须的配套设施,目前所有的遥控器用的几乎都是两节7号电池供电,主要原因就是单节干电池的电压是1.5V,而遥控器中的MCU的工作电压都是3-5V,需要两节电池串联,再通过LDO的变压,来输出合适的电压给设备供电。
如果用一颗DC-DC,给单节电池升压至3.3V直接给设备供电,且这个DC-DC的功耗又极低,依附DC-DC高转换效率的优势,遥控器是否就可以只用一颗电池,且待机时间与传统两节电池的保持一样呢。
欧创芯的OC6811就是一颗支持低电压输入,高转换效率,小体积的超低待机功耗DC-DC。
其应用原理图入下:
图1
OC6811支持0.9V-3.6V输入,因此单节干电池的1.5V就可以支持工作,直至电池电压放电至0.9V,输出电压1.8V-3.6V,输出电流300mA,其转换效率最高可达93%,相比Ldo的转换效率更高。使设备只需一颗干电池就能解决传统设备需要两颗干电池才能工作的问题。直接大幅的降低了设备的成本。且使用体验完全一致。
