【应用】用于智能手机和平板电脑的降压-升压型开关稳压器

时间： 2018-03-27 来源：Renesas

目前，由于消费者对移动设备的系统需求越来越高，移动设备的耗电量变得越来越大，导致智能手机和平板电脑经常出现的电池寿命缩短、故障和过热等问题，这严重影响了消费者的消费体验。因此，瑞萨（RENESAS）的子公司Intersil通过改善其设备的系统性能和功效，帮助OEM厂商解决ISL911xx降压-升压型开关稳压器面临的这些问题。

ISL911xx降压-升压型开关稳压器包括的产品型号有ISL91107、ISL91108、ISL91127和ISL91128。应用于移动设备中的ISL911xx系列产品可以提供系统电源管理IC（PMIC）、Wi-Fi或射频（RF）功率放大器以及其他系统外设，如相机和存储器接口。ISL911xx系列基于专有的全同步四开关先进架构，能够实现从降压到升压的无缝转换，以最低的单节锂电池电压提供高达2.5A的输出电流，从而显着提高电源效率，延长电池寿命并防止移动设备过热。

图1 降压 - 升压型稳压器应用于智能手机和平板电脑

ISL911xx降压-升压型开关稳压器的主要特点：

·输入电压范围1.8 - 5.5V

·在升压和降压模式间自动、无缝转换

·可延长电池寿命以及电池电压的使用范围

·效率可达95%（ISL91108），96%（ISL91107、ISL91127、ISL91128）

·切换频率：2.6MHz（ISL91108），2.5MHz（ISL91107、ISL91127、ISL91128）

·静态电流：45μA（ISL91107），27.5μA（ISL91108），30μA（ISL91127、ISL91128）

·ISL91107采用2.15mm x 1.51mm WLCSP封装，ISL91108采用2.34mm x 1.72mm WLCSP封装，ISL91127和ISL91128均采用2.15mm x 1.74mm WLCSP封装
