The TMI3410 is a 1MHz constant frequency, current  mode step-down converter. It is ideal for portable  equipment requiring very high current up to 2A from  single-cell Lithium-ion batteries or other input source  from 2.5V to 5.5V input voltage and the output voltage  can be regulated as low as 0.6V. The TMI3410 also can  run at 100% duty cycle for low dropout operation,  extending battery life in portable systems while light  load operation provides very low output ripple for  noise sensitive applications. The high switching  frequency minimizes the size of external components  while keeping switching losses low. The internal slope  compensation setting allows the device to operate with  smaller inductor values to optimize size and provide  efficient operation. The TMI3410 is offered in a 5-pin,  SOT package, and is available in an adjustable version.  This device offers two operation modes, PWM control  and PFM Mode switching control, which allows a high  efficiency over the wider range of the load.
