TMI2286D is a wide input voltage, high efficiency active CC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. TMI2286D provides up to typical 3.5A output current at 5V output. Maximum 100% duty cycle could be obtained. TMI2286D internal integrate high side PMOSFET (25mΩ@VIN=12V, 40mΩ@VIN=5V) and low side NMOSFET with 25mΩ.The external PMOSFET can be paralleled between VIN and SW to reduce voltage drop in application. Advanced production features include UVLO, Thermal Shutdown, Soft Start and input OVP.
