TMI2282Q 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. TMI2282Q provides up to typical 3.5A output current limit at 5V output with floating ISET pin. Switching frequency can be set by external resistor. Maximum 100% duty cycle could be obtained. TMI2282Q internal integrate 75mΩ high side and 40mΩ low side power MOSFET.

Advanced production features include UVLO, Thermal Shutdown, Soft Start and input OVP.

  • Car Charger/ Adaptor

  • Rechargeable Portable Devices

  • General-Purpose CC/CV Power Suppliers
