Tps54232evm-415 2-a, Swift ™ Regulator Evaluation

This user's guide contains background information for the TPS54232 as well as support documentation for
the TPS54232EVM-415 evaluation module (HPA415). Also included are the performance specifications,
the schematic, and the bill of materials for the TPS54232EVM-415.
The TPS54232 DC/DC converter is designed to provide up to a 2 A output from an input voltage source of
3.5 V to 28 V. Rated input voltage and output current range for the evaluation module are 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 TPS54232 Regulator The switching frequency is internally set at a
nominal 1000 kHz. The high-side MOSFET is incorporated inside the TPS54232 package along with the
gate drive circuitry. The low drain-to-source on resistance of the MOSFET allows the TPS54232 to
achieve high efficiencies and helps keep the junction temperature low at high output currents. The
compensation components are external to the integrated circuit (IC), and an external divider allows for an
adjustable output voltage. Additionally, the TPS54232 provides adjustable slow start and undervoltage
lockout inputs. The absolute maximum input voltage is 30 V for the TPS54232EVM-415.
