我看bq24075数据手册,上面关于OUT的介绍:System Supply Output. OUT provides a regulated output when the input is below the OVP threshold and above the regulation voltage. When the input is out of the operation range, OUT is connected to VBAT except when SYSOFF is high (bq24075 and bq24079 only). Connect OUT to the system load. Bypass OUT to VSS with a 4.7 μF to 47 μF ceramic capacitor。想问一个问题,当输入没有时,只写到OUT is connected to VBAT except when SYSOFF is high 不知此时out输出电压是否稳定。我们的系统需要有适配器供电时稳压到4.5-5.5v和适配器掉电时由电池供电稳压到4.5-5.5v,如果bq24075不能实现,麻烦推荐一个型号或方案,不胜感激。
