TMI2245F 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. TMI2245F provides up to total 4.8A output current at 5V output with force PWM operation. Switching frequency can be set by external resistor. Maximum 93% efficient be obtained at 4.8A and 5V output. Two current sensor pins ensure two channel CC control. TMI2245F internal Integrate 40mΩ/internal high side low side power MOSFET. Advanced production features include UVLO, Thermal Shutdown, Soft Start, OVP.
