意法半导体’的单电感同步降压-升压转换器支持高达3 A的工作电流，整合了4个低导通电阻功率MOSFET，节约了PCB板空间，降低了功率损耗，从而成为锂离子电池供电应用的理想之选。

降压-升压稳压器的主要特性包括：

  • 宽输入电压范围（1.8~5.5 V），满足了所有主电池解决方案的要求
  • 高开关频率（高达3 MHz），实现了更小巧的设计（缩小了无源元件的尺寸）
  • 全套监控：同步、电源良好和电池电量低检测
  • 轻负载条件下的节电模式提高了效率
  • 典型效率：> 94%
  • 输出电流能力高达3 A
  • < 1 μA的关断电流延长了电池寿命

它们主要用于输入电压可以从VIN - VOUT > VIN 变为  VIN - VOUT < VIN的情况。
