The TPS54550 dc/dc converter is designed to provide up to a 6-A output from an input voltage source of
4.5 V to 20 V. Rated input voltage and output current range for the evaluation module is given in
4.5 V to 20 V. Rated input voltage and output current range for the evaluation module is given in
This evaluation module is designed to demonstrate the small printed-circuit-board areas that may be
achieved when designing with the TPS54550 regulator. The maximum EVM input voltage of 17 V, is the
result of the 3.3-V output voltage. The switching frequency is internally set at a nominal 700 kHz. The
high-side MOSFET is incorporated inside the TPS54550 package along with the gate drive circuitry. The
