Tps54550 Swift ™ Regulator Evaluation Module

This user's guide contains background information for the TPS54550 as well as support documentation for
the TPS54550EVM-158 evaluation module (HPA158). Also included are the performance specifications,
the schematic, and the bill of materials for the TPS54550EVM-158.
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 Table 1 .
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   low drain-to-source on resistance of the MOSFET allows the TPS54550 to achieve high efficiencies and
helps to keep the junction temperature low at high output currents. An external divider allows for an
adjustable output voltage. External compensation components accommodate a wide range of output filter
components. Additionally, the TPS54550 provides an enable input. The absolute maximum input voltage
is 20 V.
