RT6190G 是一个4开关的Buck-Boost控制器，设计用于将输入电压转换为等于、高于或低于输入电压的输出电压。 RT6190G 的操作电压范围广，从4.5V到36V，输出电压可以通过外部FB引脚设置为3V到36V。 </br>RT6190G 实现了峰值电流模式控制机制，以平稳地在Buck、Boost和Buck-Boost模式下运行。 它还通过外部SS引脚实现可调软启动功能。 凭借I2C兼容接口，RT6190G支持许多可编程功能，包括切换频率、电源路径控制、无需修改外部电流感测电阻的CC输出功能。 此外，RT6190G 集成了输入UVLO、过压/欠压保护、周期电流限流保护、短路保护和过温保护等全面保护机能。 </br>RT6190G 采用WQFN-40L 5x5封装。 建议的结面温度范围为-40°C至125°C。
