The TPS54618EVM-606 is a fully assembled and tested circuit for evaluating the TPS54618 6A, 2MHz synchronous step down SWIFT DC/DC converter. The evaluation module operates from a 3V to 6V input and delivers a 1.8V output at 6A. The same board may be modified to provide different output voltages. This evaluation module is designed to demonstrate the small printed circuit board (PCB) areas that may be achieved when designing with the TPS54618 regulator. The switching frequency is externally set at a nominal 1000 kHz. The high side and low side MOSFETs are incorporated inside the TPS54618 package along with the gate-drive circuitry. The low drain to source on resistance of the MOSFETs allows the TPS54618 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.
