The TMI32080 is a high integrated synchronous  step-down converter with up to 8A output current  capability and input voltage range from 4.5V to 18V.  TMI32080 adopts advance COT control mode and  has fast transient response performance that could  reduce external component count. It integrates  very low RDS(ON) MOSFETs and offers high  accurate reference voltage. TMI32080 offers many selectable functions which  supports different application requirements by  setting external components flexibly. PFM  operation mode provides high efficiency in light  load condition and FPWM operation mode has  better output voltage regulation accuracy.  Selectable switching frequency provides wide  application range to trade off efficiency, solution  size and cost. Selectable current limit and  programmable soft-start time help to control power  up inrush current. Robust protections are  integrated in TMI32080 including shut down over current protection, output UVP, input UVLO and  OTP functions. TMI32080 is available in QFN3.5x3.5-18 package.
