The TMI3113 and TMI3113B are 1.0MHz constant frequency, current mode step-down converter. It is ideal for portable equipment requiring high output current up to 3A from single-cell Lithium-ion batteries. They 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 of TMI3113/TMI3113B could minimize 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. TMI3113 has power good function and it is offered in 6 pin, TSOT23-6 package. The TMI3113B is offered in 5-pin, SOT23-5 package with adjustable output voltage without PG pin.

These devices offer two operation modes, PWM control and PFM Mode switching control, which allow a high efficiency over the wider range of the load.
