The TPS54302 is a 4.5-V to 28-V input voltage range, 3-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 TPS54302 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
In the TPS54302, the frequency spread spectrum operation is introduced for EMI
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.
