TPS54202 2A Synchronous Step-Down Converter

Texas Instruments TPS54202 2A Synchronous Step-Down Converter is a 4.5V to 28V input voltage range, 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 SOT23 package, TPS4202 achieves the high power density and offers small footprint on PCB. Advanced Eco-mode implementation maximizes the light load efficiency and reduces the power loss. In the TPS54202, the frequency spread spectrum operation is introduced for EMI reduction. Cycle by cycle current limit in both high-side MOSFETs protects the converter in the overload condition and is enhanced by a low-side MOSFET freewheeling current limit which prevents current runaway. Hiccup mode protection will be triggered if the over current condition has persisted for longer than the present time.
