Texas Instruments TPS54202H Synchronous Step-Down Voltage Converter

Texas Instruments TPS54202H Synchronous Step-Down Voltage Converter is a 4.5V to 28V input voltage range and a 2A synchronous buck converter. The device includes two integrated switching FETs, internal loop compensation, and 5ms internal soft start to reduce component count. By integrating the MOSFETs and employing the SOT-23 package, the TPS54202H achieves a high power density and offers a small footprint on the PCB. Advanced Eco-mode implementation maximizes the light load efficiency and reduces power loss. Cycle-by-cycle current limit in both high-side MOSFETs protects the converter in an overload condition. The Texas Instruments TPS54202H 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.
