The TPS54202HEVM-716 is a fully assembled and tested circuit for evaluating the TPS54202H synchronous step-down SWIFT™ converter. The EVM converts a 4.2-V to 28-V input voltage to a regulated 5-V output voltage that delivers up to 2 A. The TPS54202H enables small designs by integrating the MOSFETs, internal compensation, and implementing current mode control to reduce external component count. Efficiency is maximized through the integrated 148-mΩ/78-mΩ 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.
