3 Description
The 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 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, which run out-of-phase,
reducing pulse current noise significantly.
The TPSM82480 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. The
power save mode can be switched off using the
MODE feature.
The device offers a Power Good signal and an
adjustable soft start. Also, the device features a
Thermal Good signal to indicate 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.
