Description
General part information
TPS54308 Series
The TPS54308 is a 4.5-V to 28-V input voltage range, 3-A synchronous buck converter. The device includes two integrated switching FETs, internal loop compensation, and 5-ms internal soft start to reduce component count.
By integrating the MOSFETs and employing the SOT-23 package, the TPS54308 achieves high power density and offers a small footprint on the PCB.
The TPS54308 operates in force continuous conduction mode (FCCM) during light load conditions. The switching frequency is maintained at an almost constant level over entire load range.
