在电池供电的便携设备中,设计者要使用升压转换IC。这些芯片通常会提供一个有固定电压或可调电压的输出。有些芯片带有LBI/LBO(低电池输入/低电池输出)功能。芯片制造商做这些引脚的原意是用于监控电池低电压的情况,当电池用完时发出警告。不过,这一功能还可以用来产生一个额外的电压输出。 In battery-powered portable devices, designers are using boost conversion ICs. These chips usually provide a fixed voltage or adjustable voltage output. Some chips feature LBI / LBO (Low Battery Input / Low Battery Output). The intention of the chip maker to do these pins is to monitor the low battery condition and warn you when the battery runs out. However, this feature can also be used to generate an additional voltage output.
