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.
