TPS54308DDCR Datasheet PDF - TI

●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 the high power density and offers a small footprint on the PCB.

●The TPS54308 operates in force continous conduction mode (FCCM) during light load conditions, the switching frequency is maintained at an almost constant level over entire load range.

●Cycle-by-cycle current limit in both high-side MOSFET protects the converter in an overload condition and is enhanced by a low-side MOSFET freewheeling current limit which prevents current runaway. Hiccup mode protection is triggered if the overcurrent condition has persisted for longer than the present time.
