Texas Instruments' TPSM82480 is a synchronous step-down DC-DC converter module for low profile point-of-load power supplies. The input voltage range of 2.4 V to 5.5 V enables operation from typical 3.3 V or 5 V interface supplies as well as from backup circuits dropping down as low as 2.4 V.

The output current is up to 6 A continuously provided by two phases of 3 A each. These run out-of-phase, reducing pulse current noise significantly.

The TPSM82480 provides automatically entered power save modes 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. The pulse skip mode for very light loads can be switched off by using the MODE feature.

The device features a power good signal and an adjustable soft start. Also, the device features a thermal good signal to detect excessive internal temperature. The output voltage can be changed to a preselected value by VSEL pin. TPSM82480 is able to operate in 100% duty cycle mode.
