RT6213A/RT6213B

3A峰值, 18V, 500kHz, ACOT® 降压型转换器

RT6213A/RT6213B
New

RT6213A/B 为高效率的DC/DC单片式同步整流转换器，输入电压范围从4.5V至18V，输出电流至3A。RT6213A/B采用的ACOT架构可增进瞬时响应的表现并固定操作频率。逐周期形式的限流机制可在输出短路时提供电路保护作用，缓启动机制则可消除启动瞬间的输入电流涌浪的问题。此外RT6213A/B提供输出低电压保护、输出过电流与过热关机保护功能。

应用

  • 机顶盒
  • 可携式电视
  • 路由器
  • DSL 解调器
  • LCD 、电视
