TMI3331 and TMI3331A are wide input voltage, high efficiency step-down DC/DC converter. TMI3331 operates in force PWM mode with adjustable switching frequency, and TMI3331A operates in PFM mode at light load condition. TMI3331 and TMI3331A provide up to 3A output current. Switching frequency can be set by external resistor. TMI3331 and TMI3331A internal Integrate 80mΩ high side and 60mΩ low side power MOSFET, which allows a high efficiency over the wider range of the load. Advanced production features include input UVLO, thermal shutdown, soft start and input and output OVP.

The TMI3331 and TMI3331A require a minimum number of readily available standard external components and is available in an 8-pin ESOP ROHS compliant package.
