TPS54202H Datasheet PDF - TI

●The TPS54202H is a 4.5-V to 28-V input voltage range, 2-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 TPS54202H achieves the high power density and offers a small footprint on the PCB.

●Advanced Eco-mode implementation maximizes the light load efficiency and reduces the power loss.

●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.

●For all available packages, see the orderable addendum at the end of the data sheet.
