TPS62480 2-Phase Step-Down Converter

Texas Instruments TPS62480 2-Phase Step-Down Converter is a synchronous step-down DC-DC converter for low-profile point-of-load power supplies. The input voltage range of 2.4 to 5.5V enables operation from typical 3.3V or 5V interface supplies as well as from backup circuits dropping down to as low as 2.4V. The output current is up to 6A continuously provided by two phases of 3A each, allowing the use of low-profile external components. Both of the rails are running out of phase which reduces the pulse current noise significantly. The TPS62480 provides an automatically entered power save mode to maintain high efficiency down to very light loads. This incorporates an automatic phase adding and shedding feature using both or only one phase according to the actual load.
