The TMI3411P is 1.0MHz constant frequency, current mode step-down converter. It is ideal for portable equipment requiring high current up to 2A 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 TMI3411P 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. TMI3411P has power good function and it is offered in 6 pin, SOT23-6 package. 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.
