Part Description
The TPS54202 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 SOT23 package, the TPS54202 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. In TPS54202, the frequency spread operation is introduced for EMI reduction. spectrum 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.
