TPS54425EVM-608

EVALUATION BOARD, SYNC BUCK CONVERTER.

The TPS54425EVM-608 is an evaluation module for TPS54425 4.5V to 18V Input, 4A Synchronous Step Down Converter. The TPS54425 is a single, adaptive on time, DCAP2 mode, synchronous buck converter requiring a very low external component count. The DCAP2 control circuit is optimised for low ESR output capacitors such as POSCAP, SP CAP, or ceramic types and features fast transient response with no external compensation. The switching frequency is internally set at a nominal 700KHz. The high side and low side switching MOSFETs are incorporated inside the TPS54425 package along with the gate drive circuitry. The low drain to source on resistance of the MOSFETs allow the TPS54425 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The TPS54425 dc/dc synchronous converter is designed to provide up to a 4A output from an input voltage source of 4.5V to 18V. The output voltage range is from 0.76V to 5.5V.
