TPS54202H Series

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. The TPS54202H is a 4.5-V to 28-V input voltage range, 2-A synchronous buck converter.
