The TMI31602A is a 2.3MHz switching 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 TMI31602A 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 TMI31602A adopts small size DFN1.6x1.6-6 package.
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.
