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