The TPS54335AEVM-010 is a fully assembled and tested circuit for evaluating the TPS54335A synchronous step-down SWIFT™ converter. The EVM converts a 8-V to 28-V input voltage to a regulated 5-V output voltage that delivers up to 2 A. The TPS54335A enables small designs by integrating the MOSFETs and implementing current mode control to reduce external component count. 96.5% efficiency is achieved through integrated high-side and low-side MOSFETs, low quiescent supply current, and pulse skipping at light loads. Using the enable pin, shutdown supply current is reduced to 2 μA by entering shutdown mode.
