TMI3112H

The TMI3112H is a 2.3MHz 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 while still achieving  over 95% efficiency during peak load conditions with  5V input and 3.3V output application. The TMI3112H 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 TMI3112H can supply up to 2A output load current from 2.7V to  5.5V input voltage and the output voltage can be  regulated as low as 0.6V. 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 TMI3112H 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.
