The TPS54040EVM-456 is an evaluation module designed to demonstrate the small printed circuit board areas that can be achieved when designing with the TPS54040 regulator. The TPS54040 DC to DC converter is designed to provide up to a 0.5A output from an input voltage source of 3.5V to 42V. The switching frequency is internally set at a nominal 700KHz. The high side MOSFET is incorporated inside the TPS54040 package along with the gate drive circuitry. The low drain to source on resistance of the MOSFET allows the TPS54040 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The compensation components are external to the integrated circuit, and an external divider allows for an adjustable output voltage. Additionally, the TPS54040 provides adjustable slow start and undervoltage lockout inputs. The absolute maximum input voltage is 42V for the TPS54040EVM-456.
