TMI2243数据手册Tollsemi中文资料规格书

描述 Description

TMI2243 is a wide input voltage, fixed 5V output voltage, high efficiency active CC step-down DC/DC converter that operates in either CV (Constant 5V Output Voltage) mode or CC (Constant Output Current) mode. TMI2243 provides up to typical 2.75A output current limit at 5V output. Maximum 100% duty cycle could be obtained. TMI2243 internal integrate 75mΩ high side and 40mΩ low side power MOSFET.Advanced production features include UVLO, Thermal Shutdown, Soft Start and input OVP.
