The TPS54202x is a 4.5V to 30V 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 SOT-23 package, the TPS54202x achieves the high power density and offers a small footprint on the PCB. TPS542025 has fixed 5V output which saves BOM by further reducing FB resistors. TPS542021 has adjustable output by a different FB resistor configuration.
The TPS54202x operates in pulse frequency modulation for high light load efficiency and reduces the power loss. The frequency spread spectrum operation is introduced for Electromagnetic Interference (EMI) reduction.
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.
