TPS54350EVM-235: 3.3V @ 3A, 6 ~ 18 Vin

The TPS54350 dc/dc converter is designed to provide up to 3-A output from a nominal 12-V (6-V to 18-V) input voltage source. Rated input voltage and output current range is given in Table 1−1. This evaluation module is designed to demonstrate the small PCB areas that may be achieved when designing with the TPS54350 regulator and does not reflect the high efficiencies that may be achieved when designing with this part.

The switching frequency is set at a nominal 500 kHz, allowing the use of a relatively small footprint 10uH output inductor. The high-side MOSFET is incorporated inside the TPS54350 package along with gate drive circuitry for an external synchronous FET. The low drain-to-source on resistance of the MOSFET allows the TPS54350 to achieve high efficiencies and helps to keep the junction temperature low at high output currents.

The compensation components are provided external to the IC, and allow for an adjustable output voltage and a customizable loop response. The TPS54350 is a full featured device including programmable undervoltage lockout, bidirectional synchronization, adjustable switching frequency, enable and power good functions.
