TMI2282H数据手册中文资料规格书

描述 Description

TMI2282H 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. TMI2282H provides up to total 2.8A output current at 5V output with floating ISET pin. Switching frequency can be set by external resistor. Maximum 100% duty cycle could be obtained. TMI2282H internal integrate 55mΩ high side and 30mΩ low side power MOSFET.Advanced production features include UVLO, Thermal Shutdown, Soft Start and input OVP.
