The TMI32120 is a high integrated synchronous  step-down converter with up to 12A output current  capability and input voltage range from 4.5V to 18V.  TMI32120 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. TMI32120 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 TMI32120 including cycle-by-cycle  current limit, output UVP, input UVLO and OTP  functions. TMI32120 is available in QFN3.5x3.5-18 package.
