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 A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。
